This dvar Torah is on the importance of not wasting time.
One thing wrong with addictions to technology or shmuts is
that it takes away so much time from our lives. This vort is
just meant to give chizuk be"H to use our time more carefully for it is
the only thing money can never buy back - it truly is a gift from Hashem!  

Shavuot has no special misvot, is dateless in the Torah, and has no special name.
It lacks the recognizable characteristics of a festival or special date which are present
in all other holidays. But why? Isn't Shavout one of the most important holidays in our history?
It is the time that we became Hashem's people and received the Torah - the purpose of creation.
So why doesn't the Torah have any special characteristics that distinguish it from all other
festivals just like the other festivals which each have their own uniqueness? (Ex: Pesach we have matza, sukkot we have the lulav and sukka, on Hannukka we have the menora, Purim we have megila, etc.) 

To further understand the question we have to understand a fundamental yesod
of Avodat Hashem. Life is full of potential. Wasted time equals wasted potential.
In this world, the ikar is the effort while the result is the tafel, as pirkei avot (4:17) says
"יפה שעה אחת בתשובה ומעשים טובים בעולם הזה מכל חיי העולם הבא" and (5:23) "לפום צערא עגרא".

What do we start doing unique from the second night of Pesach?
We begin counting seven weeks. What is so special about Sefirat Haomer?
It is the time that Am Yisrael prepared themselves to receive the Torah.
During this time they went from the 49th level of tumah to the 49th level of kedusha.
This period of preparation is a period full of potential - a time when we put in our hishtadlut
to become worthy of receiving the kedusha that is entailed with the holiday of Shavout
and the receiving of the Torah. However, although the Torah says to count seven weeks
it does not say the date that will be the 50th day. Why? Hashem is hinting to us to never
stop maximizing our potential and to make proper use of our time. If Hashem were to tell
us that Shavuot is on the 6th (or 7th) of Sivan then we would think that the potential
ends on this date. But it doesn't! Every minute is a potential for growth. This is why bitul Torah
and bitul zman is such a big sin (one of the only sins that Hashem is reluctant to forgive)
because it is in essence wasting the gift of potential that Hashem bestows on every human. 
As pirkei avot (3:4) says, "וְהַמְפַנֶּה לִבּוֹ לְבַטָּלָה, הֲרֵי זֶה מִתְחַיֵּב בְּנַפְשׁו" - one who turns his heart to 
idleness, this one is liable for his life. 

It was only after seven weeks that we became worthy of receiving the Torah - after
maximizing our potential. People that waste time are returning to the state we were
in Egypt when Pharoah limited our potential by not providing us with straw. The
Pharoah of today's generation is technology and most people today are slaves to
social media, movies, etc. The word for straw is תבן which is related to the word בינה - insight.
The Torah is called בינה as the pasuk in mishlei says "לי עצה ותושיה אני בינה לי גבורה." The Pharoah 
of today's generation is depriving us of Torah by bombarding us with distractions 
and enticements and very quickly our potential for a holy life and growth is wasted. 

The addictiveness of technology and the wasted time that results from it is
robbing today's generation of the Torah. How? As stated before, wasted time equals
wasted potential. Time is a necessary component in doing preparation (hishtadlut) - a
necessity in receiving the Torah, as Pirkei Avot says (2:12) "התקן עצמך ללמוד תורה שאינהּ ירושה לך".
Prepare yourself to learn Torah for it is not inherited to you. Every person has to
toil to acquire Torah and this can only be done through constant preparation.
Not for only seven weeks but throughout your entire lifetime. For this reason
Shavuot is called "weeks" and not the day we got the Torah - because the preparation
will be over the weeks of your life and is the ikar in your avoda. The uniqueness of Shavuot
is that we have a period of preparation right before it to remind us of the importance of
using our time properly. (Of course technology can be used for learning and can be used
for avodat Hashem as well, which is an ingenious invention of the Satan to test the
generations before Moshiac.) The special "mitzvah" we do on Shavuot is we stay up
learning the Torah making sure we don't waste a minute. We are telling Hashem that
we recognize that we have wasted much time through our lives but from now on we
want to get serious. We will stay up learning Torah and we will be more meticulous
in the future with how we spend our time and maximize our potential. 

"Rav Haim Palachi (Izmir, Turkey, 1788-1869) composed a work entitled Mo’ed Le’chol Hai,
in which he discusses the unique qualities of every Hebrew month and the significant days
in each month. In his discussion of the month of Sivan – the month in which we received the
Torah, as we celebrate on Shavuot – he writes that this month is especially suited for developing
the qualities of humility, unity among the Jewish people, and clear comprehension of Torah.
He then adds that the sins of Bittul Torah (wasting time that could be used for Torah study),
gossip, slander, frivolity and other forms of inappropriate speech are particularly grievous
during the month of Sivan. Although these offenses are certainly considered sinful
regardless of when they are committed, violators are liable to especially harsh retribution,
Heaven forbid, if they commit these sins during the month of Sivan. As this is the month in
which we receive the Torah, and we are to devote ourselves – and especially our faculty
of speech – to studying the Torah, these violations committed during Sivan have a particularly
harmful spiritual effect in the heavens." (Daily Halacha by Rabbi Eli Mansour) Therefore, it
is incumbent upon us to take the lesson of Shavuot to heart and be especially careful in the month
of Sivan and in the future with how we spend our time making sure to minimize our bitul Torah.

The Torah is compared to water. Water is tasteless, colorless, and odorless.
Water also lacks the characteristics that are present in other physical substances.
Water is a necessity for living things to grow and survive. So is the Torah.
Shavout is a time that we got the Torah, but now what? If you have water but you
do not drink it or water other living things with it then of what use is it? So too,
we have the Torah and we need to use it on ourselves and teach it to others.
If we don't follow its laws, study it, and use it to change then of what good was
it becoming Hashem's chosen nation and receiving the Torah? For this reason,
Shavuot does not have the unique characteristics of other festivals because
receiving the Torah wasn't the goal nor the end. The goal is to study the Torah
and follow its laws to properly serve Hashem, our Loving Father.
