If you learn from your mistakes, then they are nothing but progress. And be prepared to learn a lot.
Gaming on a monitor will not be a thing for you anymore for example, is one thing you will almost instantly learn, just like Balfie said.
When it comes to time investment, i can say, that i play less then before. The game sessions become more intense and you get more immersive action for your time - quality over quantity. Playing in VR is like instant vacation, an ideal thing to do after work, before getting into your home routines. Two or three Elite sessions a week and a few rounds in Project CARS here and there and my desire for playing video games is fullfilled. It sounds odd, but VR had a large positive impact on my quality of life.
