Doing the opposite of not skillfull things

Will it helpful to do the opposite of not skillfull things without having deeper knowledge of that thing ? Ex: I asked a question on **Laziness**, [here](https://buddhism.stackexchange.com/questions/37264/how-come-enlightened-people-dont-have-any-laziness) . But didn't recived a satisfying answer. So,Can being aware on laziness and being not lazy help to understand laziness ? Some other similar topic : conceit
