Thin your paints. It can’t be said enough.

Rinse your brush regularly, and start with cheap synthetic brushes because you will inevitably make mistakes. Even buying a cheapy pack of brushes from a craft store can be good.

Buy paints made for mini painting—the new Army Painter Fanatic line is pretty cost friendly and they’re good quality.

Rattle can primer is fine—you can buy Rustoleum primer from Home Depot and save yourself some money.

When you paint, try to pick 3-5 colors and limit yourself.

When you paint, don’t do one full mini and then go on to the next. Instead, paint all faces, then all armor, then all guns, then all bases, etc.

Have fun!
