It is really hard to screw up beer. My advice to new brewers is whatever happens during your brew, don't panic and do something stupid. I see it all the time when something goes "wrong" and the brewer will make it much worse by trying to fix a problem which doesn't exist. The old saying "the cure is worse than the ailment" applies.
What kind of beers do you like? There is always a simple brew for whatever style beer you like. Are you planning on steeping grains or a simple canned kit for your first?
