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.
In order to win Championships, some tennis players take ballet to make them more graceful and light on the courts. They create habits of working on themselves while each 0.1% amounts to the whole. It may also be a word of advice to create habits around the solutions to your problems i.e. the tennis player stretching every morning before the start of the day.
PROBLEM: flexibility, mobility
SOLUTION: ballet and dance classes
My relation to the article was in reference to implementation (of a habit) and to address the 0.1% in changes that advocate for a better outcome for a solution to change. I play tennis and I must also sharpen this skill with complementary solutions (ballet) to ensure I win my matches. Again, it's about the small solution changes that add to a whole.
