Back-up plans can help you sleep easier at night. Back-up plans can also create an easy out when times get tough.
2 - Do the work
Scratch the surface of any person with rare skills and you'll find a person who has put thousands of hours of effort into developing those skills. The 10,000 hours principle.
3 - Work a lot more
If you don't embrace a workload others would consider crazy then your goal doesn't mean that much to you.
4 - Avoid the crowds
Joining the crowd--no matter how trendy the crowd or "hot" the opportunity--is a recipe for mediocrity. (Be yourself!!!)
5 - Start at the end
Decide what you really want: to be the best, the fastest, the cheapest, the biggest, whatever. Aim for the ultimate. Decide where you want to end up. That is your goal.
