I lost quite a few training years of my life studying. I also wasted time smoking and have harmed my body. There is no way I want to go back to that life, it keeps me going in the gym. I am married now and now a teetotaler, my senses are back, that helps too.
Some videos too are helpful just before going to the gym.
