All you said about yourself doesn't quite sound like you should get a PhD.

Also having a PhD doesn't automatically make your life more interesting.

Having a PhD will make you an expert in a narrow topic. So it most likely will lead to job opportunities inside this topic. If you love this topic, then it might help having a more fulfilling work life.

The problem is, it's not quite possible to really know if you're still interested that much in a topic after studying it for several years. You might be even sick of the topic after your PhD.

What you will take away from a PhD are some research skills that you could apply on different topics. But if you don't like and enjoy researching, then I don't quite see what you will really take away from a PhD.
