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.
I can't fall asleep with earplugs in. I wear earplugs and earmuffs at work, but my job involves fast-paced assembly work which provides a lot of tactile feedback to distract me from the itchy earplugs.
Also be aware any earplugs marketed as being 'for sleep' or 'for nuisance noise' block out so little noise that you are better off sleeping on your side with a pillow over your ear. Look for earplugs with an SNR of at least 30dB (preferably at least 35dB).
