there's two costs in life: money and time.

time:
— say it takes you a minute and a half to put on and tie your shoes. use slip-on shoes, and you cut that down to 30 seconds, saving 1 minute each time. say you tie and untie your shoes once a day. that's about 60 saved minutes in a month.

— say it takes you 10 views to learn or remember something. cut that down to 1 view and you'll quickly save hours, weeks and months, right?

— say you make the same food all the time. well why not make a ton at once and freeze it into portions? or cut the recipe down so it takes two minutes to prepare instead of fifteen?

money:
— cabbage is one of the cheapest foods you can buy. say that after 1 week you've suddenly turned cabbage into a super delicious, nutritious meal (kimchi, saurkraut or whatever). the more nutrition you take in, the less you need to eat overall in general. suddenly half a plate of food costs a tenth of the price and is ten times as nutritious. then you do this with more and more foods. beans become nattou, cheap pork becomes pulled pork, etc. suddenly even your most expensive grocery shopping weeks are still "cheap".

but you can do even more. those pork bones get carved into needles to sell. that onion gets regrown. suddenly you're using your pork bone needle to make your own slippers (that you can then sell if you want). you can cook food with candles (or the sun) instead of the stovetop to save electricity. because you've learnt to speed-read, and to memorize with 1 view instead of 10, and to use slip-on shoes instead of laces, and to cook food faster, you're now saving hours and hours of time and now you likely have more money too. i need to stop wasting time...

i watched more memory-training videos. i really have to master this stuff, it'll really improve my life...
