I did an online confidence test (yes, well...) and this was part of my report. The minute I read it I knew I wanted to share it.
Accentuate the positive. Put your energy into emphasizing your better qualities rather than trying to be an unrealistically "perfect" person.
Cut yourself some slack. Just because one incident goes badly, don't assume its result is determinant of how other situations in your life will turn out.
Accept yourself as a whole person. Try not to be so judgemental of your less favourable qualities. Learn to love the entire package that is you.
I thought all of the ideas conveyed here were good. I really need to pay attention to all three.
