At a certain point in your life, you realize that you are who you are.
That isn’t to say that your life won’t change. Of course it will change. So will your personality, but not in big ways. If you’re an introvert, you’re not going to suddenly feel energized by hanging out with a room full of happy strangers who want nothing better than to engage you in mindless chitchat. And vice versa.
You may be able to change some of your habits, if you’ve got the willpower. Of course, if you don’t have willpower to begin with, you probably won’t be able to do too much about those habits, unless they’re going to kill you. That can replace willpower.
This is the stage at your life when you can be happy with who you are, if you accept it. But that’s the hard part of this process. You have to give up on some idealized version of yourself, and accept the being you are at the moment. You have to stop living in some perfect future, and hang out in the present.
But you can always get a new haircut.
This hat recalls the iconic headgear worn by the Cognition Brigade during the Second Robotic War.

This is the device that instantly turns Soylent Green and other flavorings into a soft-serve treat. The unit combines frozen Soylent Green and any additional Soylent products you can scavenge and instantly churns the ingredients to produce a treat with the texture of frozen yogurt or soft-serve ice cream, but without the crushing existential angst of eating people. 
This is a six-foot Christmas tree that pops up instantly and is pre-decorated with original artwork by renowned holiday artist Thomas Kinkaid, all of which can dispense Viritron’s patented Santa Virus. 
This is the robotic vacuum that navigates autonomously through your home up to seven times per week, where it can either clean your floors or patrol for intruders. The unit’s specially designed dual, counter-rotating agitator brushes spread carpet fibers and enable the vacuum to remove hair and other detritus from low- and high-pile carpets, while its dual Class VII lasers are capable of vaporizing any intruders (or more likely, unwanted refuse left on the floor).
