Is it worthwhile spending 10 years staring at Times and Sales data?

Do you think everything you need to know can be gleamed from T&S?

Personally I think it is possible to trade profitably from T&S alone however you might want to use other tools to track volume and price distributions. For my methods I want to know how all traders are likely to be positioned. You cannot see how multiday position traders are likely to be position from a T&S you might want a graph.. The intraday traders can be tracked on profiles and T&S. All info traded info is in the T&S anyways.
 
In my view T&S is only relevant if you are trading on an intra-day basis and many people don't.
