homerenovision for many things. i wouldn't say it's always the "textbook" approach to a lot of situations, but he'll point you in a direction to get the job done & make it look good to the average eye. it's aimed towards a homeowner & not a perfectionist. he also has good videos on which tools are actually necessities etc

if you want to master drywall (good luck, that shit is wizardry), best to work through vancouver carpenter's videos for awhile & hope you have the genetic artistry to eventually pull it off
