learning to surf backside

So I'm at the point where I'm trying to learn bottom turns and I spend all my time out in the water waiting for the lefts and ignoring the rights since I'm goofy foot. I've taken off on a right a handful of times but I feel like I should get better frontside before learning backside.
When is the best time to start learning how to surf backside?
Should I concentrate on learning frontside first with the logic that once you know how to surf one way, it'll be easier to pick it up the other?
Thanks!
