Hi,
the reason that some events occur despite seeming doubts and fears is because of the focus that a person places on certain certumstances, on the relevence to them.
Each person is unique so it is impossible to know exactly without knowing thier unique beleif system but just as a person who beleives the intelect is the most powerful tool they have, will focus their attention into their intelect and ignore other aspects of themselves, it does not mean that the odd emotional or psychic experience will not cone their way sometimes. A person who beleives that they will triumph over adversity will do just that in whatever way is relelvant for them.
For me it comes down to what does a person want to experience in their life. someone who wants to prove that even though they do not beleive in themselves they can still acheive AB or C will focus their attention and energy into just that and it will come about with enough focus.
The important thing for me is that I know I create my experience and I choose to focus my attention on aspects of myself and events that are pleasurable. In doing so i can create a great experience even if I have some doubts about myself on other areas. I work on those areas of doubt and in doing so create an even better experience in light of my own unique wants and desires.
