Sorry to hear, I would use it as an opportunity to innovate with what you do. For me this would be transitioning to a niche player or a big corporate leader (depending on which ur in now) Look to take your skills across into consulting perhaps?
id be very careful about those ‘dream job’ type ideas depending on your stage of life/ responsibilities. recently did a photography course and the trainer spent a significant portion of time complaining about the number of people that come on his courses to set up a photography business… their expectations/reality gap was usually significant (ps this is not a dig, you may be a fantastic photographer who could make it pay, there are many who arnt)
