Today I went the the gym to lift when I really didn't want to.
I was actually asleep after work and tricked myself into waking up to go. I told myself I could get an espresso on the way! I lied. I didn't have time to get one. Only enough time to get to the gym and do my routine. I didn't notice that I lied to myself until just now. But, I'm happy because I could have totally slept through the gym session and then felt guilty...which feels worse than not getting the espresso I promised myself.
TL;DR: Mind Games.
