Success and rest don’t sleep together.
Yup, human beings need sleep, I know that. But I also know that sleep steals a lot of time. Time you could spend studying, training, working or even enjoying yourself, going out, reading a book etc.
Success needs effort and time so you should not be a person who likes to sleep 10 hours per day if you want to see results (in less than 40 years).
Make it a habit to sleep less then you are used to and work on still being fit anyway. It works, trust me.
