Your top 3 and your number 7 aren't random thoughts during Christmas time. The top 2 and number 7 should be with you all year as they are important life things. The rest of them are thoughts and wishes. If you suck at Battlefield after all this time I would guess you enjoy playing and continue to suck or give it up.
Unless you plan to shave your head totally I would strongly suggest you don't even think about giving yourself a haircut. At least the hair on the top of your head.
