This is somewhat related to being adaptable, although it’s not quite the same. I talk to many people that often complain about certain aspects of their lives but don’t do anything to change what they are complaining about. 

If you do the same thing you will get the same results. But if 
you don’t like the results, why do the same thing?

Some people may have got unhealthy by eating too much junk food and not doing any exercise. They wish they could become healthy, but continue to eat junk food and not exercise. 

The idea here is to change your behavior to change your life. So if you’re unhealthy, start eating healthier food and start exercising. These will make you feel healthier. 

The sum of all your behaviors is what has given you your current life, so it’s logical that you need to change those behaviors if 
you want to change your life.

If you find change difficult, then just start small and work your way up to bigger changes. 

If you currently don’t exercise, then you don’t need to start exercising at the gym for an hour every day. You can start by just walking to the store every day, taking the stairs instead of the elevator. 

Those little behavioral changes will lead to bigger changes and also to a better life.
