Act on what you know now so what you don't know can be unveiled
Too often when we are going for something we want in life we fixate on the things we don't know how to do. The problem with that is you're setting yourself up for failure. If you focus on what you can't do, you won't be able to do it because that's what you're thinking and believing. INSTEAD, you should focus on the things you can do that will get you towards that goal you have. As you do the steps you know you can do and believe you can do, the steps you may not be able to do will become apparent and not some crazy mystery anymore as they will seem to fall into place and/or you will end up talking about what you're trying to do and someone will offer a helping hand.
