Everyone and no one

Two things are always not true:

Everyone likes this.

No one likes this.

Sorry.

If you try to please everyone, the few you don't delight will either ruin your day or ruin your sense of what sort of product you should make.

And if you believe the critic who insists that no one is going to like what you made, you will walk away from a useful niche.

One other thing: Sometimes it's easy to confuse, "the small cadre of people I want to impress because my ego demands that this 'in' group is important," with "everyone." They're not the same.
