Sometimes, people have life problems that can be entirely solved by doing one thing. (doing X made my life 0.1% better, PERMANENTLY!) These are not things like "This TAP made me exercise more frequently", but rather like "moving my scale into my doorway made me weigh myself more, causing me to exercise more frequently" - a one-shot solution that makes a reasonable amount of progress in solving a problem.
I've found that I've had a couple of life problems that I couldn't solve because I didn't know what the solution was, not because it was hard to solve - once I thought of the solution, implementation was not that difficult. I'm looking to collect various one-shot solutions to problems to expand my solution space, as well as potentially find solutions to problems that I didn't realize I had.
Please only put one problem-solution pair per answer.
Problem:
Spending too much time using your phone each day (surfing, messaging, watching videos, ..etc.).
Solution:
Change your phone's display settings to only display in grey scale.
Notes:
I saw this tip online a long time ago, and have tried it on several occasions to break an addiction to my phone (where I was glued to my phone for hours daily).
It's shocking how well this trick works. You realize after using your phone in this mode for a few days how effective colours are in getting and keeping your attention, all in the name of getting you more "engaged" with apps / your phone.
One the one hand, this one-time solution gets rid of all these temptations wholesale, on the other hand, it's almost nauseating to use the phone for a long period of time in grey scale. I don't know why, but I will literally end up tossing my phone away in disgust after a few minutes of using it in this mode, thereby very effectively solving the original problem.
