I do think that we, as more advanced homebrewers (some more advanced than others), look back at our first few batches, and we look at all of the things we would do differently now and don't want others to make the same "Mistakes" we did. However, We all made beer. And if we are still here, that beer was good enough to keep us making more until we got where we are today. You can be as simple as you would like, or as complex as you would like, it will all make beer. As long as sanitation is good, and fermentation temps are close, it will probably be the best beer you have ever had.
and always remember the homebrewer's motto: Relax, Don't worry, and have a homebrew (you can sub commercial beer in for now).
We will give you all sorts of advice here, don't worry about telling us that we are going too far. This group is a bunch of people who are obsessed with homebrewing, so we can get a little fanatical.
