We're excited to have you here @swiftpain (Joseph). Please ask about anything you might be unsure about, but aside from that just have fun. Beware that Steemit can be very addicting too, but surely more healthy than other addictions, as the real addiction here is in the connections you make with others.
I can also relate with your journey so far as I have reinvented myself several times throughout my life - in fact one has recently begun here on Steemit.
