So idk what happened but recently I've been very bored and unsatisfied with the way I look. I realized I've had the same haistyle for the last 5 years and I wanna change it but I don't know what to do

First I thought of dying it black or blue because those are 2 things I've always wanted to try but I'm afraid I end up hating it because if I do it there's no going back (I'm blond)... But on the other hand, I'm also a bit afraid to cut it because I've had ''long'' hair all my life, and it won't grow back quickly enough.
Here's two pictures or my hair:
I was hoping I could get from ideas from you guys. So... What should I do?
I guess you could also use this thread to post your current hairstyle or something like that, if you want to
