I shot a film more than one year ago, independent, no budget and the only thing I regret or will change for my next film is #2 "Finishing/Shipping is More Important Than Achieving Perfection", it kills me that I had no time to shoot how I wanted and I ended up rushing everything to have a finished product, i do have a finished product but as a filmmaker I can not film again the same way, I will work harder to get the extra money i need to take my time and make everything as perfect as can be because that's my motivation.
Other than that i pretty much agree with everything else.
