'Man's mind, once stretched by a new idea, never regains its original dimensions.' Oliver Wendell Holmes
Sometimes, you seem to be stuck in old patterns and ideas. If you want to change something for the better, though, you need to challenge your old way of thinking.
Here are some ideas on how to do that:
1. Engage in creative exercises like painting, making music, and playing creative games, 2. Learning something new either in your current area of expertise or something completely new, 3. Change elements of your lifestyle like meeting new people, taking a new route to your work, starting a new hobby etc.
