Reality forms around your commitment to succeed.
Your desires will in time externalize themselves into concrete fact.
If you're willing to pay the price any of your circumstances will change. If you want something badly enough, you're sure to get it.
Obstacles don't matter very much. Pain or other circumstances can be there. But, if you want something bad enough, you'll find a way to get it done.
You only have to love a thing greatly to get it. Desire is the fire of life.
