I feel honoring and respecting one's self is very important.
I do the diet and exercise, with my goal being to get bigger. For me, weight lifting is a bit of a spiritual experience. While not inherently so, I find a lot of peace in focusing my energy to push myself harder and farther than I have ever been.
In everyday life, I try to stay true to myself and others. I think a lot about what I say. I tend not to say things like 'See you tomorrow!' if I don't plan on seeing them tomorrow. I feel that is ultimate respect. While not necessarily making me popular with everyone, at the very least I am real with them, and myself. I find this leads to less problems in the long term.
I keep myself entertained. My mama always told me,'Being bored is an insult to yourself'. I live by those words. I may not always be out running laps, but I am never bored, no matter how dull my situation.
However, my favorite thing to do for myself is to smile. I learned from a young age, no matter how bad I felt, miserable I was, if I just smiled, I would be happy. I find it can be infectious, and it's a disease I am willing to spread.
Good post, would like to see what other people have to say.
