CronkPhilosophy is great, read some philosophy. The whole field of philosophy is more or less old people with beards theorizing the optimal way of living your life. Going to the gym can make you confident in one way, but knowledge in general is another strong path to confidence.
Some introductionary books I recommend:
Thus Spoke Zarathustra - Fredrich Nietzsche
Meditations - Marcus Aurelius
Pragmatism and Other Writings - William James
The Ego and Its Own - Max Stirner (spooks)
Sophie's World by Jostein Gaarder is another good book that covers some history of western philosophy (I can't remember if it covers philosophy from other parts of the world). It is also a novel so probably an easier read than jumping straight in to pure philosophy.
