Literature deserves its prestige for one reason above all others - because it's a tool to help us live and die with a little bit more wisdom, goodness, and sanity.
If every tool, when ordered, or even of its own accord, could do the work that befits it... then there would be no need either of apprentices for the master workers or of slaves for the lords.
Have pity on those who are fearful of taking up a pen, or a paintbrush, or an instrument, or a tool because they are afraid that someone has already done so better than they could.
