There is a great man called Alan Watts. I implore you all to seek out his knowledgeable words of wisdom, because once I stumbled upon his works I have been completely at peace with my inner self. It is an unlikely resource, as he does not have anything to do with game, yet is a philosopher with some truly life changing ideologies many of which are derived from eastern cultures. You can find plenty on him on youtube so I won't drop a specific link.

If you're struggling with inner confidence, inner peace, or inner happiness I shit you not, this is a gold mine.
