Today, when you go to bed, tell yourself that you can and will make it. This means going to bed with determination to make it; to be somebody.
When you wake up in the morning, repeat this resolution. Tell yourself you can and will make it.
Let this thought saturate your mind. And to it, marry action. In other words work your self to the last bit of your energy, not once, not twice, not thrice, but all the times, all the days, all the weeks, all the months and all the years, until you make it.
