Really agree with the author's point that there is something fulfilling about inconvenience and struggling.
After I started fishing in my spare time, I've had really good days where the fish are hammering my lures and I'm catching them every 10 minutes. Those days always start out well, but towards the end it's almost boring since I know they'll end up biting and there's no sense of accomplishment.
But the days where the fish aren't biting and I have to switch out lures, tie different rigs, and search for the fish make it much more rewarding when I do catch one.
So, if you have any money leftover you should maybe look into picking up a hobby. If you don't want to spend anymore then the default is to save it.
