What do you do for self-care, if anything?

I personally make sure to take breaks, go on walks to get some fresh air, and when I get stuck on something try to just detach and do something else. When I come back to it I have shifted my perspective and I usually find the answer or solution to whatever I was stuck on :)

Take some time to laugh!

My golden rule is whenever I feel overwhelmed, I occupy my mind with something else (walking does not work for me, because I continue to think about that subject). Anything that makes me forget the 'stuff' works: gym, games, tennis, seeing friends. I had a post about that earlier. Will paste it here in case if it is relevant to someone in this post: "Stress is often a good thing. It keeps us awake and activated. Stress moves from a life-saving to a life-threatening mechanism when it shifts from acute to chronic. Chronic stress is often for founders, especially in the early-stage phase. But if founders know how to fight it, the stress levels can be decreased significantly. With that in mind, we decided to gather and curate all the best resources about founder well-being and add them to our resource directory. Please share any resources or advice you have regarding stress management, and we will make sure to surface it in front of thousands of founders. We found few that we liked more than others. You can access them on Knowledgehunt website. Use the 'Well-being' filter to easily find them. Hoping to reduce the overall stress levels in founders even a very bit."

Giving myself permission to take breaks and stop for the day when a problem becomes incredibly monotonous and isn't making way. That definitely helped me detach from the "grinding" beat-yourself-up mindset when taking time away from a problem. When I was in college, one instructor had a great insight like you said @cederlund - taking a quick walk. Often just taking a walk away from the problem/idea/etc can be enough to get your brain flowing. Sometimes you just need to think about something else. Great question! Interested to see what other people do.
