It's easy to do ratzon Hahem when it feels good. But the real thing is when you don't feel good about it. It's the purest when you don't get any satisfaction. לפום צערה אגרא And it's not just the reward that is so much more (100 times as much) it's also the cleansing effect that it has on you.
On the other hand if you try to be happy about this monumental accomplishment, the simcha shel mitzvah has a tremendous power. R' Tzvi Meir qoutes from I-forgot-who, that while a mitzvah that's hard is worth 100 easy ones; a mitzvah with simcha is worth 1000 that are not with simcha. R' Tzvi Meir adds that it follows that if it's hard
and you try to have simcha, it's 100,000 times as powerful than "regular".
