Motivation OR Discipline???

Hello everyone! So the question for today is quite simple I would say...

Motivation or Discipline? You get to choose only one.

I used to watch so many youtube videos like 'the best motivational video ever' etc. But it rarely gave me any results in my performance. I was executing whatever I was doing at the time but never made it consistent for more than a couple of days. So I went back and watched another video to keep me motivated. It was like a hunger that I had to feed in order to continue executing.

I changed everything now, I trained myself how to be self-disciplined and built some habits and never again had to reignite the spark within me to get my results and achieve my whatever goals.

How does it work for you? Let's discuss.
