Congratulations! Yep, quite an accomplishment. We always preach about doing it with an instructor but you managed to get it done by yourself. Very impressive and we all are very happy for you!!
Now, do what your instructor suggested. There are a few things that you really need to get instruction on, especially emergency procedures, particularly dead stick landings and cross-wind landings. And, I'm sure there are more things to get brushed up on, but those are probably the most crucial for now.
Ok, so get some buddy box time for those procedures, but don't let that get in the way of having fun!! Enjoy the hobby. Toss in some practice landings while having fun and get some fuel burned. My instructor always told me that the best way to learn is to burn fuel. Get that thing up there and practice practice practice.. and of course, have fun, fun, fun.
