After all, what matters is to look back and smile. It is analyzing the work and judging it, if not good, fair. And to see that the intention was not corrupted, and that we did not run away from what had to be done, and that it was done. If the work done now displeases, if it does not fit in with today, that is also good, because change is good and it is good to learn. All that matters is to look back and smile.
