Perfection and grandiosity are a thing apart, but certainly you care about quality... Otherwise you'd play video games with fake chemistry instead of study real chemistry, no?
Quality is something that seems much more useful than perfection and grandiosity (to me at least), but I won't care about it more than necessary to get something done: if a desired reaction can be done with 80% concentration of the compounds… I wont strive for 99.9%, esp if the costs (time/money/etc) of achieving the latter are an order of magnitude higher unless it is needed (and rarely it is).
