Worthless
Someone will find your work worthless, and he will ignore it. Worse, he might choose to share his opinion with others.
OK. We have that established.
Now, what are you going to do?
Are you going to let the opinion of someone else — an opinion that cost nothing to give, but will cost you everything to absorb — will you let that opinion stifle you?
Or will you recognize that your work... your heartfelt, passionate work... is not so mediocre and unremarkable that it will be accepted universally?
That your work is different? That it will resonate with some, and not with others?
Ignore the critics; they don’t care about your journey.
Besides: your work was never for them in the first place.
