Well I think depends on what you are looking to create, however, I have found it quite easy for me to just switch direction a bit and carry on, making what some think to be a mistake, (including myself!) into part of my plan. Those mistakes have actually become part of my style! I have had several issues with my vision in recent years that have left me in a spot so to speak. Good news is I CAN and do still create what I consider great work! LOL so you see, sometimes we just have to roll with the punches!
