To develop faith try using affirmations. Some say affirmations don't work. The truth is they're working too much, using force. Force negates so trying harder isn't the answer. Or these folks don't persist. They affirm for a week or month than say that affirmations don't work.
The 2 requirements for successful affirmations:
1 - Inject feeling into your affirmations.
Dance. Jump around. Act like a clown. Seriously, the lighter you can feel the more effective. I used to stand around and repeat statements like it was a job. This attracted boring and dull situations. When I began to move while performing affirmations the statements began to come true.
2 - Persist.
Most of us have loads of programming specifically designed to prevent our affirmations from coming true. To overcome this programming you must persist. Eventually your subconscious mind will accept the idea and proceed to make it true.
What's your experience with affirmations?
