Looking for the next level

Ok, so i just recently got hacked, story in another thread, and one of the suggestions from you fine lads, is to go ahead and use this as an opportunity to do something I normally wouldn't, and break out of my normal grind. With that in mind, I have always been a solo player, minus messing around with friends, but nothing like raids or anything like that. There is a ton of content I haven't explored because I hoarded all my good stuff like a dragon, but now it's gone. What's a good next step to go from skiller, to the next level. I have a 99 in smithing and am like level 104. Thank you in advance.
