There's no easy way out. I realised that my body is the temple of my existence. I realised the importance of a nutritious diet. You needn't diet. You can live it.
Regular exercise is almost like an education.
You've gotta make the rules, you stick by it. And try not to hurt anyone. It's believed that you don't relax. That you don't ever chill out. My idea of chilling out is eating at proper hours, getting enough sleep.
