You are not wandering about because you are afraid of commitment, but because you are expanding your skill base and your possibilities. At a certain point, when you are ready to settle on something, ideas and opportunities will inevitably present themselves to you.

And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.
