At the emotional level there is no time - you either have an emotion or you don't. Have the flexibility to go on changing what you do until you get what you want. If you go on doing what you've always done, you'll always get what you always got. You can change the deletions, distortions and generalisations that aren't working for you, until you get the results you want. Choose your beliefs carefully - they tend to become true.
Beliefs are self-fulfilling prophecies.
If you believe you can't do something, you probably won't be able to - even if everything else you need to do it is in place. When you have an answer to these questions, you have discovered your own personal time line - the way in which you organise your memories. Most forms of psychotherapy have a similar aim but rely on bringing repressed material into conscious awareness, whether by talking about early events or by reliving them through hypnotic regression. However, as you may have noticed, you can understand all the reasons why you have a problem and still have it.
