I think my biggest struggles with maintaining a primal lifestyle are still trying to have a social life with my college friends. Oftentimes we drink, eat party-type food, and stay up late having a good time. While that is all well and good, I dearly love my friends, it is not very conducive for a primal lifestyle.
The every once in a while hot chocolate or dessert can send me spiraling down a sugar binge. I haven't done a binge in quite a while (yay!), but being in college makes sticking to primal pretty challenging.
But like sarahz said, you have to really want it in order to make these improvements to your life
Two important questions to ask yourself every week:
Did I run faster and farther this week than I did last week?
Can I lift more weight and do more repetitions that I did last week?
