I recently had the realisation that I need to take it easy instead of trying to fix everything around me.
This has been most noticeable at work - I switched companies within the larger group as I had felt that I could make more of an impact at the new company.
While there are multiple interesting challenges and growth opportunties, I've been too fixated on trying to mould company B into company A - an impossible task - which has caused more frustration that spills into my personal life and affects my mental health.
Sometimes you just need to take it easy.
Have a slow day at work, block out the noise and focus on something that brings you some pleasure.
Go for a walk.
Explore a side-project.
Go to bed early.
