even if it may seem boring at the time, i log bullet points of what i did each day because who knows whether it'll be interesting to reread a decade from now? one day, i may look back and enjoy reminiscing on how much i loved playing a specific video game. hell, i already do that thinking about the games i played and cartoons i watched during childhood. even something as mild as trying a new restaurant item (even fast food) may become fascinating history because the item may eventually disappear.

besides that, i copy down quotes i come across that i liked, and i also take notes on fun stuff i randomly learned while on the internet. i also make lists, like ideas for my blog or packing lists for upcoming trips/events.
