Life Hacks
Remembering Things
Medication
Sometimes I forget if I have taken my medication.
You can get a pill box that has the days of the week on it, and for each day, a compartment for morning, noon and night. So if you forget if you have taken your pills, you can just look at the box.
Another way I did was to write down the timing on the medication itself.
This probably won't work for liquid medicine so you can try noting down when you have taken it.
Daily Journal
I find that having a daily journal helps in a lot of things. One example is when checking my credit card bill and I cannot remember what I bought, I can check what happened on that day.
You don't have to write in detail. Just simple notes like "went to the mall" or "had dinner with friends".
