Feynman: I am burned out and I'll never accomplish anything

He wouldn't have even thought to make the parallel between the wobble and how electron orbits move in relativity if he didn't already have a good understanding of electron orbits, and it wouldn't lead to the Dirac Equation in electrodynamics without him being familiar with that, then quantum electrodynamics without being familiar with that.
So yes, while play and working on things 'with no importance' can lead to great discoveries, or something of importance later, you need to have that background of knowledge and the habit of connecting two disparate concepts together or else it will always remain something 'with no importance'.

Now that I was unemployed, I had even more time to play with physics!

I was being facetious though. While the story is interesting, it should be considered in the current context.
A huge swathe of senior researchers are burnt out but the wisdom Feynman imparts isn't particularly helpful to them due to the nature of academia today.
I have a few scientific projects that I play around with when I'm stuck on my "totally serious stuff I'm supposed to work with" which give publications at some point, but that's more of a side-effect than anything else.
And of course scientists now bullshit an extraordinary amount when it comes to future applications of their work - they often don't particularly care, the MBAs just want to hear their mantras.
"Most children are already physicists. Sadly, our education system beats the curiosity out of them"
Was that Feynman or someone else?
What's interesting about the underlying implications of all these quotes to me is that what makes a good physicist, a good artist, or a good anything, is the unabashed curiosity, a willingness to experiment without being stopped by fear of failure, and the state of play that one must be in to unleash creative approaches and new connections.

Code however you want. Don't let programmers who pose as authorities fool you into thinking you're 'doing it wrong', that kills all the joy in programming. As long as you're thinking through things and it works, and especially if you're actually enjoying it, you're most certainly doing it right.
He started out having fun with physics, worked very hard to accomplish tangible things with it, and burned out because that made it stop being fun (to the point where he found it "disgusting"). He started playing again, doing things that were completely useless, and that lead to his greatest discovery.
