Stepping out of your comfort zone and learning new stuff is meant to be uncomfortable.

If you're a writer you'll spend lots of time in a state of confusion (also known as creative anxiety). You're always starting a new project, and no matter how experienced you are, you'll never stop facing a blank computer screen.

If you're not aware that confusion is a highly creative state, you'll tend to let confusion paralyze you. Instead of accepting that this state is both natural, and good, you try to get out of it.

Read "Confusion is good" for an excellent exercise which prevents your confusion from paralyzing you.
