I think the one thing you can do that will have a good impact on every area of your life is going to the gym. If you work out regularly and keep healthy, you'll look much better and you'll be much more confident, and it acts as a personal goal that you work towards every day. Go to the gym and work on yourself (pursue personal projects, improve your mindset etc) and you'll find that everything else improves.
