Like being rejected when asking for a date, all rejection gets easier over time. You also find out like any art, people have varied views of what they consider good. Just ask someone to name a great movie. Either you will get the same cookie cutter responses like Citizen Kane or a fight over one person thinking their choice is good and the other is complete crap. The point is the creator needs to write what they enjoy and accept that there will be those who won’t like it.
