The Work You Put In Will Always Pay Back, Daymond John

Work always pays off. There is never a time that you do work and it was a waste. Too often I hear people talk about putting in work only to have a project canceled, a business go under, gained 2lbs even though I worked out and watched what I ate. This wasn’t wasted time. Maybe it helped you fine tune a skill, maybe it taught you a lesson that you will learn from and grow from to prepare for the future.
