Clarify: If you don't know what you're aiming at, you'll never hit it.
Commit: It's easy to talk about what you want to achieve, but a little more difficult to take action. Don't just know what you want to do, take steps towards doing it.
Clues: People have done what you want to do before. Find out how they did it and get clues. Don't just make it up as you go along. It will waste your time.
Change strategy: If what you're doing isn't working, don't keep doing it. That's silly. Change your strategy.
Stick with it: Don't stop just because it doesn't excite you anymore. You know the 10,000-hour rule? It takes about 10,000 hours to become great? Well, it's there for a reason. Most people give up too quickly. Don't do that.
