Being good enough is pretty easy. We don't need to strive to better ourselves each and every day. It's safe. Goals are achieved. Progress is made. No-one really gets hurt. Except of course that's not true.
For most of us, good enough is, well, good enough. We never achieve the heights of which we are capable, and we avoid the painful lows involved in getting there. Perhaps it's out default mode?
Whatever our endeavor we should always be asking 'is this good enough'? I have found that the answer is always a resounding 'no'.
The secret to creative success is therefore knowing when to let go.
