"Motivation comes from working on things we care about."- Sheryl Sandberg.
When you are motivated, your ideas will jump at you because they get you.
The things you care about will not start to look good because you care about them, you need to love them enough to keep at them and with a spirited level of motivation.
You will be motivated beyond where the universe sets as the place for you to be if that care is pushed beyond the level where it should naturally be at.
Be about that desire and follow your heart. There is no need wasting your time worrying if you will fail. Failure will be your stepping stone to win and you should not be afraid of it. Fail forward.
