Yes you can do it, then you'll be Yoseph Hatzadik
You just have to want to, sign up for the 90, it really helps, but do it a day at a time.
Remember your/our nisayoin isn't harder than Yosef Hatzadik's. and in his merit the sea split. A Peshat I heard, he changed/controlled his nature, that of a 17 year old youth, so therefore the sea changed it's nature and split.
What did Yosef do, he ran out, that's what we have to do too, whether it's running from the internet, or aggressive Shmiras Enayim.
You may think at this point, I did, it's my nature I can't change that, well the truth is you can, the sky is the limit, if you push yourself a little, the Siyata Dishmaya is limitless.
