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.

Buy new blanket that isn't falling apart. Semi-permanently reduced the ugh field.

If I take "Doctor diagnosed X" as strong evidence that I have X, then I should find the latest treatment guidelines/summary articles for X once a year. Led to a possibly permanent treatment algorithm (full or nearly-full symptom management) for 2 chronic problems with little to no side effects. Also caught a medication error with the acquired knowledge. Also a found a treatment that greatly helps (but not eliminates/prevents) another chronic condition.
May also have turned up a life-altering diagnoses but that is to-be-confirmed by real medical experts.
>general knowledge acquisition
Using Sci-Hub. Reduces the "Relevant article in PubMed based on the abstract->paste the PMID->oh, this is useful" loop to <1 min.
If necessary, I can try to quantify the benefits of the above items but it's a little like the RENT song about measuring a year.
