How to motivate myself?

How to motivate yourself?

This is one of my largest problems I have now. I have to find a work placement for my next academic year, but actually I’ve just sent my CV to few companies.

My methods of motivating myself are:
1. Change the place/ mood
2. Don’t think too much

Basically my character tends to be too careful about anything, so when I need to take some action, I try to think it is not a big thing if I make a mistake. However, they don’t work well so far. Maybe now is the time to learn a new way to solve the problem.
