To solve any problem or to reach your goal, you don't need to know all the answers in advance. But you must have a clear idea of the problem or the goal you want to reach.
All you have to do is know where you're going. The answers will come to you of their own accord. Don't procrastinate when faced with a big difficult problem, break the problem into parts, and handle one part at a time.
If you can get up the courage to begin, you have the courage to succeed. It's the job you never start that takes the longest to finish. Don't worry about what lies dimly at a distance, but do what lies clearly ahead.
Your biggest opportunity is where you are right now. Once you begin you're half done. When you realize you want to spend the rest of your time doing a particular thing, you want the time to start as soon as possible…
