There's the white knuckle approach to life. Grinding through the pain. Alternatively, you can search for things you actually like.

In business, finding work that you like.

In fitness, finding workouts that you enjoy.

In health, finding foods you like that are good for you.

Lastly, you can't make people want to change. You can only guide them once they show that they want to change. This is different from wanting a result. Someone who wants to be more successful is very different from someone who wants to learn how to work more effectively. Focus on process over end goal.
