Never doubt yourself, even a little bit.
Case note; Guy in the gym lifting, has the arms out, and this other gym rat says, "You're looking really good, man!", que my entrance, and I'm ready to pose down right there. Guy pulls his shirt up, yea, real cut up abs, so I move to the play nice mode. After a minute a flexes his bicept in the mirror and I follow suit; I'm only about twice this guys size! Am I F'n serious?! Yea, since moving to bulk mode I have smoothed out a bit, but you can still see them. The only thing that was too small on me was my confidence in the moment.
I'm not trying to come across like I need to challenge and compete with every guy I see. Been there, done that. But when there is a chance for some friendly comparison, I will punch my own ticket from now on.
It's 2:00 and I am downing my fourth meal of about 1/2 pound of lean beef and 8 oz. of potatoes. That is not including a protein drink with a scoop of ice cream in it I had right after the gym.
I forget who said it, and I paraphrase, "I am focused 24/7, and if your not focused 24/7, when we meet, I'll win."
Too F'n right!
