I'd add to not do a lot of crazy experimental beers to start with. You can get to those later. Better to start with some of the more standard fare and dial in your process. That way you know you're doing it right. THEN you can start doing weird ****.
I've known a ton of guys who always do experimental beers and nearly always make ****ty beers. I tell them to try to just make a few basic beers, an APA or Stout or something and they reply that they like to experiment. Okay. That's cool. But it's resulting in a ton of ****ty beers. Figure out your process first. Get it down so that you're happy with your beer, then you can get to the crazy stuff.
And make a damned starter for god's sake (if using liquid yeast). It's not THAT much work. *Not* making a starter will never result in a better beer than making a starter. You might be lucky and have no problem, but why risk it when you're putting in all of the effort to brew the beer.
