First step - write down a list of positive affirmations you think apllies to you.
You can find good examples of affirmations at page 47 of Louise L. Hay's book already mentioned.
Second step - Choose 1 to 3 affirmations and wrtie them on coloured post-its and place them in places you can see easily.
Then repeat them loudly 3 times each, when you get up, before going to sleep and at any other occasion you feel like saying them.
Last step - put a sample of these affirmations in your success file.
Believe me, this is a very powerful exercise. Repeat it for at least 30 days.
