I agree. Get some tools and give it a try. A couple things I’d add are that when soldering a connection, attempt to make a good mechanical connection first, such as twisting wires together, making a secure loop though an eyelet, etc. and then applying the solder. Also, keep in mind that the solder will run toward the heat so the iron goes on one side of the connection and the solder is applied to the other side and it will then run into that mechanical connection.
Yes, obtaining the correct solder is important. Don’t use the type used in plumbing. I use a 60/40 rosin-core solder that is .032” diameter for general electronics work. My iron is 25 watt. Occasionally I use a solder paste flux to clean the connection. Since removal of old solder is sometimes required, I use a solder sucker, essentially a spring-loaded vacuum. The only other tool I find invaluable is a “third hand” which is a heavy metal base that has an adjustable armature with alligator clips on the ends. It can hold the parts while the dolding takes place.
Like mentioned, this stuff is available at Harbor Freight. If one really gets into it, a “soldering station” with adjustable power, solder vacuuming system, lighting, and such can be obtained. It’s pricey.
