Isn't everything on Internet a solution to some such small problem? Like the other day I came across a good review for a small portable dishwasher - https://www.youtube.com/watch?v=hVup5ya0WVQ .
But the key as you say is noticing that we have a problem and that a solution exists for it; But if there's anything lurking in this platform has thought me is that 'Identifying a problem' is far more difficult than finding a solution for that!
