The world, and more importantly its women, is not interested in wasting its time on the games of boys; if you want to be successful you need to be a man. One of the largest parts of being a man comes down to one simple concept: handle your shit.
There is nothing wrong with being a boy, full of hope, innocence and awkwardness. But as soon as you want to be taken seriously in matters of importance you need step up your game. While I never thought I would quote the bible on this blog (or in any other walk of life) Corinthians said it best.
When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
-(1 Corinthians 13:11 – King James)
