>>120474 some bits of advice that helped me out (they contradict each other a little bit):
1: be kind to your future self. clean up your dishes, take a shower now, send that email, finish that thing, do it now so that your future self won't have to worry about it. save your quarters so she can get something from the vending machine too <3
2: live more in the present and don't let yourself get too engrossed in "i need X to happen and then Y and Z so that I don't have to A" because it can very easily eat you up. if you get a few minutes to yourself and it's a nice day outside, stand in the fresh air and enjoy it. be happy that your lunch has the right amount of sauce on it. watch a bird pick at something on the ground and laugh when it drops it. little things can make a huge difference, good and bad.
3: try stuff and mix it up! I'm in university right now and there's dinner events for my major. i'm skipping class this thursday so i can go and meet others in my field and go with some classmates. a little spontaneity keeps you sharp and i think a break in routine sometimes is good for you.
hope these helped a little bit :)
