During a recent class, a student told me he was worried by what one of his relatives might think about the story he was thinking about writing.
See the problem?
He hadn’t even put pen to paper (or finger to keyboard) but already was worrying about the reception his writing might receive.
I suggested he focus on getting the words on paper (or in the computer) first and to remember that he didn’t have to show that writing to anyone.
Tip: Don’t let you fears stop you before you’ve even begun.
