This may seem like nitpicking to some but I always recommend that newbies first follow the mfr's instructions when using their products. For example, if the mfr recommends using a stop bath then I recommend using one.
It's often true that a water bath can be substituted for a stop bath (and may even be an improvement) but what is usually omitted from this advice is that doing this results in an increase of effective development time, which in turn affects the image to a certain extent. If you do this you really should make appropriate time compensation. But, this adds complexity, something a newby doesn't need so it should be something dealt with later, after he/she has had more experience.
Admittedly, this alone won't make a huge difference in the results but when one starts getting into the habit of ignoring the basics, they do add up and
will show up in the results sooner or later. Then the newby gets the impression that he "did it right but it gave bad results" and gives up. But, the truth is, if he got bad results then he/she didn't do it right at all. The times were off, the temps were off, the chems were poorly mixed, etc. , etc. And, when you add this to all the things that can go wrong with the original exposure and darkroom printing, you can end up with a real mess. So, if you tend toward the philosophy of "close is good enough" then you'd probably be happier just shooting digital.
I don't mean to be a nazi about it but, with photochemistry, your results will be in direct proportion to how closely you follow correct procedure exactly. Strive to be fastidious with the little details and you'll get beautiful, consistent results.
