Mate, I hear you. I come home from work and hardly have any energy to pick up the guitar let alone get out and perform:-) Being a solo artist probably doesn’t help either, at least in a band you have 3 or 4 other people who can drag each other off the couch.
But yeah, for all the talk of going viral and self-publishing, the old-fashioned way of getting out into your local scene and playing is still probably the way to go. Even if you can only manage it once a week. Open mics are okay, but gigs are probably better. Another thing you can do is find out which venues host original artists and send them a few of your songs. Let them know you are available if a support slot becomes free.
