Congrats on getting it right the first time!
A couple tips for anyone just getting started fixing flats, to avoid some very common rookie mistakes:
Always check the inside of the tube for glass/thorns that may have caused the flat, (even if you think you know what caused it). I use my fingertips (lightly, so you don't get cut on it), because I've missed them using the rag method or visual only.
Never use tire levels to get the tire back on, just use your hands. Sometimes its really, really tight, but the effort it takes still beats having to start the whole process over because you just pinched your new tube between the rim and the tool.
The glue type of patch is more reliable than the pre-sticky quick patch. Let the glue dry before you put the patch on.
Make sure the tire is fully seated all the way around the rim before fully inflating it. If the tube starts bulging out somewhere between tire and rim, deflate and start over. Otherwise it will explode. Violently, and loudly.
