I had a couple of realisations recently that in hindsight should have been obvious:

I love to code, and often I even get paid to do it.

I should pause to appreciate that and have fun with my work!

I shouldn’t feel guilty when I write code…

  • that doesn’t make anyone money
  • that I might throw away
  • just to learn
  • purely for the fuck fun of it

Time enjoyed is not time wasted –Unknown

I’m not an entrepreneur.

…and I don’t want to be! I can barely even spell the word! To repeat myself, I shouldn’t feel guilty when I write code that doesn’t make anyone money. I also don’t have to worry about being a go-getter or doing other things that I frankly don’t enjoy doing.

I get paid enough to live comfortably doing what I enjoy to do. Why on earth did I feel guilty for not founding a startup?!

The thing that I should wish to obtain from money would be leisure with security. –Bertrand Russell

When Sam Aaron gave his above keynote for OSCON Europe 2015, it resonated with me. Here we were at a conference about Open Source software listening to talks about how to make money, growth hacking and business models. Where were the passionate, pointless rants about coding style, or the people that care more about code than they do about the money it can make?

So this weekend I’ll be having a go at re-writing a fairly hairy legacy Python script in Emacs Lisp. It might work1, it might not. I might finish, I might not. Someone might even care, but they probably won’t…

and I don’t care. I’m playing!

…and I’ll leave you with the words of the drummer2:

At Cornell, I’d work on preparing my courses, and I’d go over to the library a lot and read through the Arabian Nights and ogle the girls that would go by. But when it came time to do some research, I couldn’t get to work. I was a little tired; I was not interested; I couldn’t do research! … I simply couldn’t get started on any problem: I remember writing one or two sentences about some problem in gamma rays and then I couldn’t go any further. I was convinced that from the war and everything (the death of my wife) I had simply burned myself out.

Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics. Why did I enjoy it? I used to play with it. I used to do whatever I felt like doing - it didn’t have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with. When I was in high school, I’d see water running out of a faucet growing narrower, and wonder if I could figure out what determines that curve. I found it was rather easy to do. I didn’t have to do it; it wasn’t important for the future of science; somebody else had already done it. That didn’t make any difference: I’d invent things and play with things for my own entertainment.

So I got this new attitude. Now that I am burned out and I’ll never accomplish anything, I’ve got this nice position at the university teaching classes which I rather enjoy, and just like I read the Arabian Nights for pleasure, I’m going to play with physics, whenever I want to, without worrying about any importance whatsoever.

Within a week I was in the cafeteria and some guy, fooling around, throws a plate in the air. As the plate went up in the air I saw it wobble, and I noticed the red medallion of Cornell on the plate going around. It was pretty obvious to me that the medallion went around faster than the wobbling.

I had nothing to do, so I start to figure out the motion of the rotating plate. I discover that when the angle is very slight, the medallion rotates twice as fast as the wobble rate - two to one. It came out of a complicated equation! Then I thought, “Is there some way I can see in a more fundamental way, by looking at the forces or the dynamics, why it’s two to one?”

I don’t remember how I did it, but I ultimately worked out what the motion of the mass particles is, and how all the accelerations balance to make it come out two to one.

I still remember going to Hans Bethe and saying, “Hey, Hans! I noticed something interesting. Here the plate goes around so, and the reason it’s two to one is. . .” and I showed him the accelerations.

He says, “Feynman, that’s pretty interesting, but what’s the importance of it? Why are you doing it?”

“Hah!” I say. “There’s no importance whatsoever. I’m just doing it for the fun of it.” His reaction didn’t discourage me; I had made up my mind I was going to enjoy physics and do whatever I liked.

I went on to work out equations of wobbles. Then I thought about how electron orbits start to move in relativity. Then there’s the Dirac Equation in electrodynamics. And then quantum electrodynamics. And before I knew it (it was a very short time) I was “playing” - working, really with the same old problem that I loved so much, that I had stopped working on when I went to Los Alamos: my thesis-type problems; all those old-fashioned, wonderful things.

It was effortless. It was easy to play with these things. It was like uncorking a bottle: Everything flowed out effortlessly. I almost tried to resist it! There was no importance to what I was doing, but ultimately there was. The diagrams and the whole business that I got the Nobel Prize for came from that piddling around with the wobbling plate.

  1. That was a lie. I already have a proof of concept working. 

  2. Taken from Just Think of It, which was in turn taken from the biographical Surely You’re Joking, Mr. Feynman! A great read if you have the chance.
