It would be enough confidence.
Not too much to where you become cocky and arrogant
Not too little to where you are so humble you never speak up and tell anyone just how good a writer you are
But enough to keep you going.
Enough to sustain you after the latest setback or challenge – and there will be one.
Small to someone else might be mountainous to you.
Not because you are weak or sensitive, but because you haven’t traversed that mountain yet.
But you will.
