People play osu! for many reasons and farming pp is one of them. There's nothing wrong with wanting to rank up and receive the adrenaline from seeing those numbers go up, it is completely natural! You should play what you want, whatever you enjoy, it's a game after all.
DISCLAIMER: This is my own opinion. While I do believe you should play what you want, if your goal is to improve then be sure you set your expectations right!
