Start-up and entrepreneurship is not regarding ideas you have, it is regarding the execution of that idea as well as the follow-through on it. Great ideas without execution and follow-through stand nowhere even it may happen that you have an idea, but haven't executed it and the people who follow the same idea and executed may build a huge start-up. The important things one need to do, if one wants to achieve success with your idea are:
1. be confident.
2. Accept risk.
3. Define your purpose.
4. Create a plan.
5. Assemble a like-minded team.
6. Constantly build momentum.
7. Anticipate obstacles.
8. Establish a professional/personal balance.
9. Set micro-goals.
10. Be patient.
