"If I regarded my life from the point of view of the pessimist, I should be undone. I should seek in vain for the light that does not visit my eyes and the music that does not ring in my ears. I should beg night and day and never be satisfied. I should sit apart in awful solitude, a prey to fear and despair. But since I consider it a duty to myself and to others to be happy, I escape a misery worse than any physical deprivation."

Does everyone feel this way? When I was young, I was perpetually overconfident or insecure. Either I felt completely useless, unattractive, and worthless, or that I was pretty much a success, and everything I did was bound to succeed. When I was confident, I could overcome the hardest challenges. But all it took was the smallest setback for me to be sure that I was utterly worthless. Regaining my self-confidence had nothing to do with success...whether I experienced it as a failure or triumph was utterly dependent on my mood.
