Probably the most underrated advice is to look after your brushes. When I'm painting, I want the paint no more than halfway up the bristles, and ideally just sitting on the top, rather than penetrating all the way through.
If you get paint all over them, it'll dry in between them where the bristles meet the handle. This forces the bristles to splay, and eventually knackers your brush before its time.
And for drybrushing, get a dedicated drybrush - if you use regular ones, that also knackers them!
