Find out who you are

Do it on purpose, and you will find out who you are. Asking for a guarantee before you start something, you may never start. From a coaching perspective, look at a concept, an idea, or system of play with intent. Try it out, and see if it fits. Spending a lot of time figuring out who you are first, before doing something, IMO is a good way to slow down progress and learning. –Tim Brady
