is it worth it?
to spend all that time to get better
what do you get out of it
also isn't it all memorization too
Is it worth it? That is a completely subjective question that everyone would answer differently.
I like to play chess and really don't like to lose very much. So any time spent actually getting better is worth it for me.
As to memorization, it can be very important in openings but knowing the ideas is even better. Especially since most people aren't going to stay in "book" for very long and you will be on your own sooner than later.
Memorizing concrete endgames and positions is also important. However, there is a whole lot of the game where memorization won't help; where ideas, the ability to analyze and calculate are more important.
