Just go out, do some sports and enjoy life :) I stopped spending too much time in front of the computer and started doing more outdoor activities. Best decision ever.
These days I schedule my work around the weather. Few things bring me as much happiness as a day in the sun. I know it has been a good day when I have not touched my laptop once.
And actually you can combine both. Sitting with your laptop on the grass (in the shade), to get the outside feel, but still work done.
As with many things in life, though "go touch grass" isn't actually about touching grass, touching grass really is a good thing. (Well, except that it makes me itch all over the area of contact. Still worth it.)
At least, that's what works for me, sometimes metaphors are to be also taken literal.
It's a bit silly, and still very bare bones, but I just like the phrase "touch grass", and this is my effort to reclaim it from the depths of derisiveness.
I can't afford to go to restaurants all the time, and I don't like bars or the mall.
I'm shy and I don't do well around strangers, and even when I do meet new people 99% of the time we don't have much in common, so it feels like a waste of time.
I'd much rather surf the web... at least there I'm learning stuff, and I can communicate with people who I actually have something in common with.
Some things, like spending time in nature are nice once in a while, but there's no nature near where I live, and even if there was I'm often not in the mood to go.
Going to restaurants, bars or meeting strangers isn't what I meant. It's still the artificial human made world. Spend time outside the city, hiking, boarding, climbing, running or just enjoying nature... That's it. Finding like-minded people will come by itself.
Oh, and beeing active is just awesome. Pushing the body to certain limits is just so important for my mental health. I am a complete different person, if I don't do sports for a certain time.
