- Understand the difference between clean and sanitized (don’t worry about sterilization)
- Don’t believe the "experts"and the status quo.
- Make what you like.
- Disregard what others think of your brew if you like it.
- Never be afraid to experiment
- Study brewing history. You will find that nothing is new.
- Listen to Denny
- Go all grain now. Its just as easy as extract.
- Relax, its only a hobby. Stores are full of ready to drink beer in cans.
- If you are worrying about something, your priorities are out of order.

Brew often.
Always try and improve the beer.
Enjoy your beer - it is yours, and you can say I made this.
Cheers to that!
Now why would I tell someone you made my beer? 
This, and read everything you can get your hands on about brewing.
and join the AHA or, at the very least, join this forum
Forgot the quotes.
Start simple.
Too many people make the same mistake I did and start off brewing Imperial Stouts and Baltic Porters before they have learned how to manage fermentation temps, build yeast starters, or even mash - if they had started out with a humble Brown Ale or Bitter, they would probably enjoy the results earlier on.
(Probably fits in under the “R” in RDWHAHB, but) DON’T GET IN A BIG HURRY … (unless your wort is boiling over 
)
If you’re brewing a kit, take the instructions and throw them away ASAP.
Everybody forgets the 4th ingredient: water.
But it comprises 95% of the beer.
It makes a huge difference if you’re unfortunate to live in parts of the country where the water isn’t ideal for brewing.
Make sure is is good tasting, chlorine- and chloramide-free, and has the necessary ions needed for good AG brewing.
Regular filtered or spring water can be used for extract batches.
I’d have to say that isn’t universally true. I’ve seen kits with good instructions as well as bad.
1 ) Forget advice about not drinking homebrew whilst brewing. A brewer needs inspiration.
2 ) Eat a breakfast burrito prior to brewing. Sustenance is important for the brewer that excels.
3 ) Remember that the only style guideline that matters is… Crap, can’t think of one that matters.
4 ) Avoid setting the dog on fire. Non-adherence to this can cause the spousal unit to curtail brewing activities and you’ll end up rethinking point of advice #1.
5 ) Buy a headlamp. Brewing in the dark sucks.
6 ) Don’t grab hot items of equipment with your bare hands.
7 ) Leave plenty of space between your nonheat tolerant equipment and your 640,000 BTU burner.
8 ) Be prepared. Have extra thermometers, hydrometers, pint glasses, cigars, and breakfast burritos on hand.
9 ) When brewing outdoors, brew in a covered space. Boiling wort attracts snow clouds. Even in July.
10 ) Send homebrew samples to me. That will allow me to give much more detailed and individualized advice. This is likely to be a very iterative process, so keep my address handy each time you package your beer.
IME, not so much. First homebrew is after the yeast is pitched. Sweet, sweet reward…
I think I’d have to agree. Safety and motivation. Good deal
I get all the inspiration I need when I have a couple beers after I brew. Drinking while brewing leads me to mistakes and laziness.
I’m with you on this.

I usually pull a pint right after flameout. It’s the reward for a job well done. 
I have found that the safety and quality control are both better if I do not drink until everything is finished, cleaned, and stored away. Then I can have a pint.
