My Rule #31
In life, it is easy for us to feel tired and give up, but life is like a marathon. You got to keep going, no matter how slow you may be getting, because as long as you don't stop, you will be able to cross the finishing line.
I've been back to the gym and I realize the lesson from gym. Keep going. It does not matter how slowly you go in life, as long as you do not stop.
