I find that when we really love, accept and approve of ourselves exactly as we are, then everything in life works. Accept yourself as you are. Praise yourself as much as you can.
Criticism breaks down the inner spirit, praise builds it up.
It may be difficult at first, but keep practicing and soon you will mean and feel what you say. This process will help you get in touch with your true self. Love yourself as much as you can and all of life will mirror this love back to you. Panic and worry serve nothing. Consciously record over those old mental tapes with good, loving and peaceful affirmations.
