My “meditation” is singing along musics from power metal, symphonic metal, etc., specially the extra cheesy ones, like Blood of Bannockburn (by Sabaton), Keeper of the Celestial Flame of Abernethy (by Gloryhammer), The Phoenix (by Fall Out Boy), Defenders of Gaia (by Rhapsody of Fire), Venom of Venus (by Powerwolf), etc. Helps me with dealing with situations of pent-up stress.
Maybe don’t care as much? First due to the stress it causes. Second, if you pretend to be someone you’re not, people may end up liking that instead, and much like with any farce, the longer it goes, the more cracks appear.
Also, something I try to do is, without worrying much for the result, to chitchat with people. If they sound/look interested, I keep going and depending on how it evolves, I might even have gotten someone who I’m going to be hanging with for years to come. If they don’t sound or look interested, I slowly drop the attempt and try it with someone else down the line.
