What are your best tips for new bread bakers?

A kitchen scale! For successful bread baking you MUST weigh your ingredients. A one cup measure of flour will vary quite a bit depending on your style (did you scoop and sweep? spoon in? sift?). A simple, inexpensive scale - mine, with a tare function, was less than $20 - will help keep your bakes consistent every time.

I would say bake the exact same recipe 10 times in a row. You'll learn your ingredients, your equipment, and improve your process.

Learn the textures, timing and visual signals that your dough is ready and/or progressing in its development. Then, use more or less flour, water, time, as needed.
Treat the recipe as a guide not a dictator.
Make two or three basic breads (maybe of different types) over and over until you master them. Then branch out to variations or other breads.
AAccept ccasional failures and keep going. If you have repeated troubles, in one area, learn from a class or a live teacher to overcome them.
Enjoy this basic skill and basic food :)

I think the most important thing is to invest in an instant read thermometer. Many recipes say to use “bath temp water” or “warm water” which is much too ambiguous to be helpful to novice bread bakers.

If your water is too warm, you’ll instantly kill your yeast. A foolproof way to avoid that is to use a thermometer.
