This is very important in life. How to get everything done and how to feel more control of life. Write down what you need to do. What you need to achieve everyday/week/month and look at those. Ask yourself what is most important? Your deadline in 2 days or watching a whole season of friends? What is more important making sure to sleep enough or exercising at 4am every morning.
The worst thing which can lead to stress and anxiety is when you realise you have no money to pay your bills or when you spend money on useless things. If you are on a tight budget it can be tough. But stick to what you can spend. Don't out yourself in a situation where you don't have the money to pay for something you need to.
In everyday life alot of energy is exerted in helping others, doing things and being on the go. But it's important to take YOU time. Whether that means going for a walk or run, sitting in your room and listening to music or just taking a long road trip or even sitting and drinking coffee with a friend can be a sort of therapy and YOU time. Just make sure to not push yourself to your limits all the time,because eventually both your head and body will give up.
Preferably everyday,but at least every week. Isolating yourself won't help you or make you feel very good. Humans need some sort of connection and communication with other people to feel their best. So don't forget that even if at times it can feel hard to socialise or you just want to hide away. It won't help you or be beneficial to you.
