I'm always doing that which I can not do, in order that I may learn how to do it.
I once knew a very religious fellow who, with almost no experience, got a job as a home construction worker. I saw him one day and asked him how it was going. He replied "Well, today the Lord taught me how to install a ceiling."
Several times in my life I have taken on the challenge of doing things I knew almost nothing about. In my late teens I was hired as an actor. I had talent and some ability but very little experience. I went to work carefully observing the other, more experienced actors around me. I bought books on the subject to give me an idea of the scope and dimensions of what I should be doing. I did a lot of homework with the script and the director's notes. I was slowly learning the craft. I did well enough to be hired again and again, and so spent most of my life as an actor. I got good enough so that a New York City critic wrote "His versatility is awe inspiring."
When I first got a job as a radio announcer, I didn't even know how to turn the microphone on. I sat down in front of a control board with a row of knobs and switches and a few meters. I tried turning them on and off while saying "Hello." Finally one of the meters flapped so I knew I was on the air. I introduced the first record, turned all the other knobs up, started the record and turned all the knobs down, one by one, until I found the one that made the meter move. From there I figured out where the next turntable was attached. By the end of my shift I knew 100% more about broadcasting than I did when I started, which was nothing. I learned even more by watching the other announcers and engineers work. Broadcasting was a part time job for me when I wasn't acting, but I was eventually welcomed as a part timer for a major market radio station in New York.
I took life drawing classes at an art school in New York. On my first day the model was a big man, over 6 feet tall and very husky. It was a 10 minute pose and what I drew was about 4 inches tall in the middle of the page. I used to keep it around just to show myself what I didn't know. I became annoyed with myself because I couldn't do it. I was at the point when most people would give up. But I signed up for classes all day, everyday, 6 days a week. When I wasn't working I was at the art school drawing. Until one day I finally saw what the instructors had been trying to show me about the human figure. Soon, the school was putting my drawings up for exhibit along with the more advanced students. And people in the class were moving over to sit next to be to see what I was doing so that they could learn from me.
I'm retired now, but in all of those areas, acting, broadcasting and drawing I can still do better. I'm no Picasso. But almost everything I've done in my life I did Picasso's way. You have to go into the water if you want to learn how to swim.

His wife answered "We fail. But screw your courage to the sticking place and we'll not fail."
