How do you know if you are going to love doing something if you have never tried it? So to do what you love, you need to be prepared to be a beginner.
If you make a leap to something new and different, it is inevitable that there will be things you need to learn. And the fact is, you are not going to get it completely right first time. That is just something you need to accept.
You can either come at it with a stubborn, frustrated, closed mind, or you can come at it as a hopeful beginner, willing, open and ready to learn. (Hint: The latter always gets better results). Once you know what you don’t know, and you commit to learning it, that is half the battle won. Consider new challenges as stepping stones to doing what you love, and suddenly they seem a whole lot more exciting.
