I don’t look at it like that. I look at beliefs as quantifiable and empirically tested (to the extend possible) trains of thought that act as an internal compass in your pursuits in life. I don’t believe you can have a belief that holds little or no weight in reality, just because it makes you feel good and alters your self image in a positive way, without running the risk of deluding yourself.
When you talked about the job you couldn’t get in The Netherlands and the situation in Budapest, what you’re talking about there is not a matter of belief — it’s a matter of explaining yourself to others. A logical way for you to rationalize your moves to the people around you. This is more in the sphere of social dynamics and relationships, than it is a belief.
The belief is that “You can and given that you work hard enough, will become a great philosopher.” This belief is then like water going downstream. All of the obstacles along the way don’t matter, as long as you keep the flow steady. The Netherlands, Budapest, a temple in Nepal, the path is not entirely certain, but the belief is the compass which guides your steps even in the darkness of uncertainty.
