I find that whenever I do anything, my motivation, creativity and even physical pain is influenced by how much energy I have. Sometimes I feel "good" and my brain is super active, I can say what I want to say, I can make the music I want, I can do physical activity with gusto and involvement. Other times I feel dull and sluggish, I DON'T want to do creative endeavors, I CAN'T come up with the stuff I want to say, and everything aches when I'm trying to work out. It's like I just don't feel like it. I WANT to feel like it.

How do you guys feel energetic? What do I need to make sure to eat? How do I need to sleep, specifically? Do I need to cut out the light coming into my room in the morning? What kind of vitamins are vital?
