The #1 mistake beginner bakers make (and it's not what you think)
Most people think the reason their first loaf of bread comes out dense and sad is because they "can't bake." It's not that. It's almost always one of two things:
Your yeast is dead or dying — and you never tested it. Water that's too hot (over 115°F) kills yeast instantly. Water that's too cold just makes it lazy. Before you mix anything, proof your yeast in warm water with a pinch of sugar for 5-10 minutes. If it doesn't get foamy, throw it out and get new yeast. This one step eliminates probably 60% of "my bread didn't rise" problems.
You're guessing on flour measurement. Scooping flour straight from the bag with a measuring cup packs it down and you end up with way more flour than the recipe intended — leading to dense, dry, brick-like results. Spoon flour into the cup and level it off, or better yet, weigh it. A $10 kitchen scale will improve your bread more than any technique tip I could give you.
Everything else — kneading time, proofing temperature, shaping — matters less than people think when you're starting out. Nail your yeast and your flour measurement first, and your bread will already be better than 90% of first attempts.
I built Crumb & Craft Baking Academy around this idea: give beginners the few things that actually matter before drowning them in technique. If you're just getting started, come bake with us — first week's on a 1-day trial.
