Is counting worth it

[RedeemerKing]

Right now i am under 21 but love to gamble. I love poker and blackjack. I want to know is it worth it to start to learn how to count. Im just a guy who would do it by myself. No teams and no pipe dreams of takin vegas for 10 million. Is it worth it to learn how to count with the way they cut the deck and the CSMs. will card counting survive or will it be cut out in say 5-10 years. Can a single guy with a modest bet size profit from it. Any thoughts would be appreciated
Thx
