Basically, the goal is to develop a deep understanding of yourself (how does a human body and mind work + what are some specificities for yourself) and your surroundings. When you understand these two processes you will apply them easier and boost your confidence. I've been working on this kind of stuff for 10 years now, and I can only tell you it can most definitely be done. You can do this by reading lots of books, acquiring a skill (for me white-water rafting, fitness, ngos, online marketing) and spirituality. Hope that helps.
