It’s always better the second time despite the annoyance 

 There’s a lesson in there 

 That would be an interesting approach for a machine learning algorithm  

 80/20 

 I bet the state of being annoyed over losing 4 hours of work took more than 20 min. 😉 

 It’s a long 20 minutes though 

 Same with design. You could spend 8 hours messing with pixels and not have anything solid, take a nap, and work it out in 10 minutes. 

This is why I just take a break if I’m stuck. No point in wasting time. 

 Funny how that works. 

 yeaaaa 

 This is very true of financial modeling as well

 Worked all day making final changes to code then the last compile of the day, I compiled the binary with the same name as the source.

I just said fuck and went home for the day.  It took other day to get the changes put back into place.

Never made that mistake again.  

 The second time round you might find yourself doing even a better job.  

 Nice. 

 and sometimes improve the solution  

 especially if you thought hard about it, and hopefully scribbled something on paper all along 

 typing is not the bottleneck

 and usually the 2nd one is better
