Set up a working hobby electronics bench. Document your kit, layout, and one safety-protocol document. Solder 20 joints and photograph the best + worst.
Don't buy gear you don't need. Tier 1 (~$200) is enough to start. Add Tier 2 when you're actively soldering.
Bench photo: clean desk, lamp, DMM on right, breadboard center, soldering iron on left in holder, ventilation visible.
20 joints: first 5 messy, joints 10-20 progressively cleaner. Visible improvement.
