If, like me, you learned to solder at the Radio Shack School of Scarred Knuckles, please save yourself twenty years of fucking around and watch this set of training videos from the 80's:https://www.youtube.com/watch?v=vIT4ra6Mo0s&list=PL926EC0F1F93C1837
Follow up with the rework/repair series:https://www.youtube.com/watch?v=HKX-GBe_lUI&list=PL958FF32927823D12
You can breeze through them in an hour or so and save yourself so, so much time in the long run.
@phooky I'm so glad you shared this. I was originally trained in "The Bigger the Blob, the Better the Job" school of soldering.
