Does Zbrush fun to you?

Hi, I’m new to Zbrush and currently spend 4hours each day trying to learn it.

I got to say it’s frustrating! But I saw a guy on a stream and the dude seams so captivated while sculpting.

So I am wondering it must be fun only once you know how to use Zbrush at the point where you could literally project your ideas and turn it into a sculpture.

Perhaps, even if you handle Zbrush well it is still as painful as trying to learn it?
