I agree 100%
When I first started chess, I wanted to be a positional master (just like those grandmasters play) Using that philosophy, I managed to earn ratings equal to players who knew a lot more about chess than me.
So I guess as a shortcut, it was great.
But it was not until I admitted that tactical chess was "real chess" also, that was finally able to break through that glass ceiling, and start making the progress that had eluded me for years. I had to realize that the best style was no style. I needed to work where I was weak.
That is why a majority of players do NOT know what to do in an endgame at all!
Even modern Grandmasters have tremendous problems here.
