It's a creative industry.  No matter how much you love what you are doing right now, you will definitely have critics.
Just let go, go sleep for three months.
Nothing in this world is fair; if you are expecting something like this, you are born in the wrong planet.
These are all about decision making by gut instinct of clients and consumers.
It's always about the chemistry.

It's not about doing things right and please your mom; it's not even about perfection.

99.9% of the products you work on will never succeed.  The moment lies on the process.
