Teacher! Thank you so much. I was trying to start a new life as an interior designer, but getting certified doesn't guarantee employment. Companies aren't schools - because of this damn industry rule, I had to learn SketchUp, and I couldn't find a course this good until I discovered you. Now I'm steadily working hard to skill up step by step. If I manage to get a job after creating my portfolio, I'll write you a thank-you letter. Thank you, teacher.
