I'm not sure about wisest decisions overall for the year, but one of the wisest decisions I made was finally getting the cyst on my back looked at and taken care of. It had been there for a while and been hurting for a while and after, seriously, a few years, I finally decided to get it looked at.
Surgery is a big deal and it was my first surgery to go through, but I'm glad the cyst is gone and I don't have to deal with it anymore! Stitches are a different story though... but at least they are now out too!
If you have anything you think is weird, anything you think is not supposed to be there, anything that is hurting you, etc. I recommend you get it checked out ASAP.
