Hi,
I think there's no problem in reading books when you are starting, but off course only when you join that with some experience you will be more successfull.
I think that's a cicle of learning, you read, you try, you analyze...imo it's the best aproach!
I usually do more of the trying and less the analyzing but shouldn't be that way.
A good aproach is also go back to books you read after a period of playing to ciment the concepts and easially fit the concepts in your game.
Last but not least, watching poker it's a great way to learn, and off course all the sites that provide video learning have a lot of customers and success!
It's up to each one of us to find the best balance for ourselfs!
Good luck at the tables!
