This is a truth that I guess I never entirely internalized, even though it's been thrown in my face over and over and over again. Even though I got it on an intellectual level, I never entirely felt it.
Life isn't about the big achievements. I can never expect anything to suddenly get better. Not my attitude, not my energy levels, not my social life, nothing. No real change is going to happen over night through some intense burst of will and strength. I'm not going to wake up suddenly able to leap a thousand miles; all I can do is put one foot in front of the other foot. Baby steps.
I keep finding myself setting these high goals and then berating myself for not meeting them. I'd go to the club (party/barbecue/whatever) and get mad at myself because I didn't magically become a socialite when I walked through the door. I'd get mad at myself for not being busy all day, even though recently I've been exhausted more often than not. And it doesn't make sense. I can't change any of this instantly, it's all a process.
All I can do is bit by bit start feeding the better parts of me instead of the bad. Feeding good habits, reinforcing good thought patterns, etc. Feeding my creativity instead of depression for example. That's what I can do, that's where the power lies. Not setting unrealistic expectations of instant change.
