I had purchased my bike with the intentions of always riding out with my buddies. Unfortunately, some have sold their bikes and some have just stopped riding completely. At one point, I thought of selling the bike but, later realized that I could ride alone and still have a great time. I guess in the end it all depends on how you feel and what will make you happy. I personally think I would have regretted selling the bike and I'm glad I didn't.
As far as learning new techniques go, have you thought about taking any of the motorcycle classes? I've only done the basic but, it helped big time especially since this was my first bike. I've heard lots of great things about the advanced session but, I'll leave that up to the people on here who have been through it to tell you their experience with it.
Whatever you decide to do, I wish you the best and please be safe! Never go past your comfort zone.
