-Years Experience about 8. Not into breeding, but just as companions.
5 things I have learned: That's tough..
-How to identify morphs more easily.
-They make great reptiles, are very easy to look after. I've had other geckos, pythons, corns, milksnakes, tortoises, beardies, iguanas, frogs, turtles etc...and the Leo's are by far my favorite!
-As someone else mentioned, listen to what others have to say, especially experienced hobbyists.
-Not for myself by others -> LEO'S LIVE ALONG TIME!!!!! I find so many are a "few months" interest thing, than they are tossed aside and mistreated.
-I guess, just a lot of basic things too. From bedding-heating-all the different types of food out there for Leo's. I know it sounds simple, but now after going through it all, those would be the main questions I see, and am asked from beginners.
[[[Since one wasn't a real thing I've learned, but more of a observation...I'll add one more]]]
-They are actually really entertaining. More so than Bearded Dragons, I believe. My geckos seem to enjoy, new hides + huts. There is so many small knick-nacks that Leo's can use. Whether it's small animal supplies or something you've seen at a craft store. Some how it can come into play with Leo's. I see it bringing out a lot of the artistic side of hobbyists who try to make their own caging + backgrounds. Or as simple as dishes. It truly is a fun hobby and with other reptiles it doesn't seem to be as much "adventure" in the possibilities you can provide for Leopard Geckos. - If that makes any sense!
Needless to say, I absolutely adore them!
I got my first gecko in 2003 (though I have a long history 45 ignorant years ago of killing pet-store anoles and iguanas) and just finished my 5th breeding season:
1. There is a natural leopard gecko yearly breeding and eating cycle
2. There is a natural leopard gecko selling cycle
3. If you know the cycle you will worry less about what your geckos are (and aren't) doing
4. Leopard geckos can exist for 24 hours in a deli cup (just learned that)
5. You can have too many leopard geckos, especially if you live in a small house.

I got my first breeding pair of leos in '99. They were a jungle female and a normal male. My mom had mad a deal with me that if I could breed them I could have a snake. She thought a 12 year old wouldn't be able to do it. Haha. I have been breeding pretty consistently since then, I missed one season completely, and have been breeding very small groups of geckos the past few years. Mostly because I had to grow up, in a sense, haha. Now that I'm getting settled as an adult, my collection is expanding again, but it's still going to stay a lot smaller than many of your's.
