A wheelie is far from a manual, and most riders take several years (years!) to learn a properly controlled manual for more than about 10-20 feet. Keep at it though.
If you are looking to ride street than work on rollbacks, endos, nose wheelies, and keep working on jumping. Time to start messing with grinds, even if it is just getting your front peg onto stuff, you want to get a feel for it.
