While I was parking my car, I saw a buff homeless guy in a tank top rummaging through trash, pushing a shopping cart. He was a bit older. He strutted and flexed just in case anyone was watching.
With all the problems he must have going for him, he still carries himself with confidence and finds time to do work out using playground equipment. Not just time, the motivation and lack of willingness to fail in this endeavor.
You got a car, a computer, a place to live, a gym membership, a refrigerator, and access to fresh foods. What's your excuse?
