You have to balance out exploiting droolers with not making yourself too exploitable. Obviously opening 10x pot is super exploitable, but with the level of play and the rake in these cash games it can often be the best sizing... but be aware that it could potentially be a huge mistake and why.

Live poker is not a great proofing ground because it takes a long ass time to get the sample size you need to know you're being profitable. If you can beat 100NL online for 2bb/100, you can probably beat live 1/2 for 20bb/100, but then you're playing about 20 hands an hour*, so in 5 hours you can expect to make $40. Subtract gas money drinks and tips and you're lucky to break even.
*just for easy math. Count the number of hands you play. It's a useful thing to know.
