I came across this article How to Create a Positive Attitude, it is worth a read.
Here are some bullets points I gathered from this insightful article by Geoffrey James:
1. Remember that YOU control your attitude.
2. Adopt beliefs that frame events in a positive way.
3. Create a “library” of positive thoughts.
4. Avoid angry or negative media.
5. Ignore whiners and complainers.
6. Use a more positive vocabulary.
