You can use positive affirmations to help you deal with feelings of worry or anxiety. The steps are simple:

1. Acknowledge the anxiety or worry you feel.

2. Identify what is causing those feelings (for instance, a job interview).

3. Stop the almost automatic stream of negative thoughts on the spot (the 'I will do terrible', 'I never know what to say' kind of thoughts).

4. Replace them with a positive affirmation ('I will be calm and collected', 'I always find the right thing to say').

Good news is, with a little bit of practice positive thinking becomes almost as automatic as negative thinking once was, and it replaces it.

You can build a positive attitude and acquire a positive outlook on life when you shift to positive thinking consistently.
