I know it sounds naive, but i realize now how important it is to be ENTHUSIASTIC about the things you do or are planning to do..
Enthusiasm creates motivation and a positive outlook.
Problems are not seen as "problems" but instead as challenges,maybe even seen as welcome because they will aid in learning.
If you are enthusiastic you are already halfway on your way to success.
You can be enthusiastic about a lot of things, eg. a challenge alone can create enthusiasm because you KNOW you will "do it" regardless of the nay-sayers and regardless of a "bad economy" or whatever hurdles you might encounter.
You can be enthusiastic about the money you will make, you can be enthusiastic about learning new things and getting new knowledge, meeting with new people etc.
