Usually its in plain sight ... try something that affects you daily.
For me its paying bills ... it sucks, so now im building something to make it suck less.
When I built my last house I also found things that sucked like components for hanging tvs on the wall. I wanted a junction box that was interchangeable and could work specifically for each tv, so I made that too.
There are probably hundreds of thousands of valuable things no one has executed well on yet, it does not mean no one has tried and just because someone has tried and failed it does not mean it is less valuable either.
