Eh brake fluid can be a pain in the arse. Its easy to contaminate it whilst changing (moisture in the air can mess with the fluid). Also setting your brakes up for a bleed can be a pain without basic mechanical knowledge and a vehicle lift.
Also brake fluid is a horrible substance in general to work with, causing pretty nasty skin reactions.
If you want to try some vehicle maintenance I would recommend changing oil, its far simpler and needs done far more often so its a good thing to learn to DIY. Brake pads are another easy and somewhat frequent one.
