Get positive thinking a chance and put it into practice. So the next time you hear yourself saying, "I've never done it before". Stop, think about it and realize, "It's an opportunity to learn something new!"
Make sure to give yourself a day off from your job search. Choose one day a week when you will not think about your job search. This will allow you time to clear your head, rest, and relax. The following day get back on your search feeling refreshed.
Try putting "I" back into your vocabulary. We often focus on family and everyone else before we focus on ourselves. Say I am going to do achieve what I want for me.
