Positive Thinking
You will acquire new skills, you will be seen as someone who can handle difficult challenges, and you may open up new career opportunities.
 
Make sure that identifying these opportunities and focusing on them is part of your positive thinking.

Tip:
In the past people have advocated positive thinking almost recklessly, as if it is a solution to everything.
Positive thinking should be used with common sense.

First, decide rationally what goals you can realistically attain with hard work, and then use positive thinking to reinforce these.
