I disagree, bad habits come naturally through practice. Trying to look for special finger-tricky ways to do algorithms, learning ways to do frequent moves fast is something you should read and try to learn, and it doesn't come naturally.
For example, doing R' U R' really fast is something I learned by reading somewhere, it's done by placing the right hand index finger on the DBR corner and the right hand thumb on the UR edge, then while doing the R' turn you have to push with the index finger so even before you finish the first R' turn, the U turn will happen quickly and once it's done you continue to do the R' turn so you get R' U R' which feels like you did just an R2.
I personally would have never picked that up by myself just from practice, it's something I read which helped me a lot.
