Children are the boldest philosophers. They enter life naked, not covered by the smallest fig leaf of dogma, absolutes, creeds. This is why every question they ask is so absurdly naïve and so frighteningly complex.
The only advice I could give is to stay positive and focused in terms of what your goals are, and stick to them. If you can't attain those goals, maybe they're not realistic. At this level only a small percentage of players make it, so you've really got to strive to get what you want.
