Don't take everything seriously

There are a few different approaches you could take to relax and not take everything so seriously:

1. Find healthy ways to cope with stress. Activities like exercising, spending time outdoors, practicing mindfulness or meditation, or talking to a therapist or trusted friend can help.
2. Prioritize tasks. If you are feeling overwhelmed by the number of things you have to do, it's helpful to sit down and prioritize tasks. This can help you feel more in control of your workload and less stressed.
3. Take breaks. Take regular breaks to rest and relax, even if it’s just for a few minutes at a time. This can help you recharge and come back to your tasks with a clearer mind.
4. Reframe your perspective. Sometimes, you can take things too seriously because you feel like there are high stakes or that everything is a crisis. See the bigger picture and put things in perspective. Remind yourself that mistakes are a normal part of life and that it’s okay to make them. 
5. Engage in activities that you enjoy and that help you relax. This could be something as simple as going for a walk or watching a funny movie.

Remember, everyone’s coping strategies are different, so what works for one person may not work for another.
