Totally agree with you. Instead of providing better products, too many apps and services abuse the approaches to "engage" their users.

I would like to be a painter.

I used to learn to paint during the whole my childhood, but I gave up to be a painter and switched to be a tech guy.

I really like paint and I do some doodles in the weekend now.

You and me both. I still paint, and it's one of the most enjoyable things I do. Although I do wonder if I switched to it full-time if it would lose its lustre.

I think it's when you start doing things for money that they loose their lustre.
