Do you stop yourself from trying to do something new just because you do not know how to do it?
It is time to take action. Depending on the nature of the stuff you want to try out, you will have to decide whether you need a person who can teach you or whether you can learn it yourself.
This is the first decision that will move you to learn and try something out.
It is important that you take that step because you never know there may be a "Picasso" or an "Agatha Christie" waiting to be awakened in you!
