As for working out, studying , and sleeping in. These all depend on my college days. Most of my time is dedicated to studying as much as I can and doing activities for cheer and Tri Delt, so whenever I get the chance to actually work out, I would most definitely rather sleep. I truly cherish the down time I have during the day, and not at night when everything is already taken care of. However, it would be to my benefit to work out so a nights rest would be far more relaxing.
Thinking about all of the areas I lack self discipline is really kind of dumb on my half. Having self discipline in these areas would be to my benefit. Even if I slowly eased into everything. I can improve these by just reminding myself that I only hurt myself when I give in, and I can only benefit from disciplining myself, even though sometimes it is extremely hard.
If you lack self discipline in studying too, you will probably like Google Pacman as much as I do.
