If you want to succeed, you must be brave to move. If you are in doubt, then the results you will get will be arbitrary. More dangerous, if hesitant stepping makes you not so step and take the path of a thousand alias escape from your dreams and hopes.
A person who still stepped, but hesitantly enveloped his journey then in fact he was walking in place alias not to the point.
Successful people must dare to step, although only one small step that started it is not wide. No matter how small you step, getting started is a courage that must be owned by people who want to get success.
To get started, you must prepare the best awareness. Full concentration on what you live, doubt is usually caused by uncertainty on what it does, does not know the consequences it does, and does not have a clear vision on the outcome that lies ahead. The point is the awareness of what it does.
Satan interferes with people with doubts, then we must convince ourselves on every thing done.
