Autocad - is it worth using?

Hey,
I have quite good Photoshop skills and would like to develop it more. Therefore, 4 years ago I had Autocad courses. I didn't like it more, it was not easy.. Today started thinking is it worth to know how to use Autocad? Is it still popular or it's already old-fashioned program? I think if I should focus more on Photoshop or should try to remember my old Autocad skills.
