Once you find something you truly love, you'll want to be a part of it all the time. Exposure leads to passion.
Giving up on your passion is not an option. It's sometimes daunting to always try to look at the long term goal. When setbacks happen (and they will), put one foot in front of the other. Break things down into sections (one step at a time) - into short term goals.
Get up and start your day early so you can get more work in to widen the gap against everyone else. Pay attention in the action that you are performing (NO shortcuts), in what you are performing, and if you can have that level of focus, you can't help but to have a certain level of obsession.
The greatest fear we face is ourselves. It's scary if you put your heart and soul into it and fail. Then how are you going to feel about yourself? Fearless is putting your heart and soul into it, and just GOING for it!
To be unyielding, ALWAYS go after it. When a challenge ensues, always go after it.
