Why The Fight?

Why do I fight against certain practices?

I have found this to be a very valuable question for my personal growth. 

Sometimes, I fight because it isn't a good fit for my life and where I am going. 

However, frequently, I fight because it's an area that requires uncomfortable growth. 

It could be fear, it could be laziness, it could be the unknown, or moving in a direction that I am being stubborn in.
