As long as you are convinced you have never done anything, you can never do anything.

‎If you keep thinking about what you want to do or what you hope will happen, you don't do it, and it won't happen.

If you spend too much time thinking about a thing, you'll never get it done.

You may never know what results come of your actions, but if you do nothing, there will be no results.

If you don't imagine, nothing ever happens at all.

If you think something hard is impossible, you’ll never even start trying to achieve it.

He who waits to do a great deal of good at once will never do anything.

If you constantly fret about timing things perfectly, they'll never happen.

Never act until you have clearly answered the question: What happens if I do nothing?

The longer you wait to do something you should do now, the greater the odds that you will never actually do it.

If I look at the mass I will never act.

If you put off everything till you're sure of it, you'll get nothing done.

You think you are simply resting, the better to act when the time comes, or for no reason, and you soon find yourself powerless ever to do anything again.

Instead of fearing what could go wrong. Fear what happens if you never try.
