For me, by far the biggest waste of time is waxing my chain.

I have to turn on the crock pot to melt it. That takes over 0.2 sec.

Then I have to put the chain in when it has melted. That also takes over That takes over 0.2 sec.

Then I have to stir it around for 10 seconds.

Finally, I have to pull it out, which again takes over 0.2 sec.

That is more than 10.6 seconds of my life I will never get back.
