If you're bored, you might as well try doing something productive like learning something new (like a new recipe, a coding language, a foreign language, how to knit, etc.), read a book, or do some self reflection. Usually when I'm bored, I just read or write or do some coding when I want to feel productive.
Shopping, dining, Bluritting, walking, biking, hiking, camping, volunteering, reading, singing, sewing, texting, talking, skipping, dancing and cooking.
Dance infront of your mirror while singing into your hair brush to the song " we belong " by Pat Benatar.. DO IT ! So awesome :)
Sit in front of the mirror and have a staring competition with your reflection. See if you can make it blink first.
Read, cook, clean out your closet.
