I read an online blog zenhabits.net which I find posts some really great bits and peices and the other day I read this rather good post/article which I think summarizes a good place to have your head at

Interesting Blog Post

I find that thinking this particular way has helped assuage my self-doubts and insecurities is just to enjoy myself. Focusing on the positive things about myself, friends and others rather than looking for imperfections and catching negative thoughts, feelings etc. before they manifest has given me the confidence that it takes to be successful in life.

I liked this article and the quote at the end, hope a few of you find it useful too...
