You can do that bit by bit. Everyday, do one thing that you really don't want to do. Everyday, refrain from doing something that you want to do and can do.
If you want to go hardcore, expand this circle of do's and don'ts over the course of a month. By the end of the month, you'll be living as an ascetic, and that is when you'll know you have mastery over yourself.
Then every year repeat this asceticism for about 1-2 weeks. Withdraw from the world, read and write, eat one meal a day. That way your control over yourself keeps strong.
