Unless you sport a beard shaving is something that you need to do every day (most of us), now because you have to do it every day if you allow it to be it can become a chore or you can make the best out of it by investing in some good kit and do a great job and feel happy about it, turning a chore into a pleasure. Before you know it you will be looking forward to your shave and you will take your time and do it well.
It's all in your mind, you can keep it as a chore that needs to be done or you can turn it into something that you enjoy, a bit of me time, so to sum up shaving is a state of mind, it's your choice, chore or pleasure. I get great pleasure from taking my time (me time) with my shave and I give myself a great shave and afterwards I feel great.
It's the same with most things in life, you can moan and drag your feet or make the most out of it and enjoy it, whatever it is. Live life, love life
I don't know if I would call it a hobby or not but It is an enjoyable past time!
