<h2>Invest in simplicity</h2>
<blockquote cite="https://en.wikipedia.org/wiki/No_Silver_Bullet"><small>
<p>“Whereas the difference between poor conceptual designs and good ones may lie in the soundness of design method, the difference between good designs and great ones surely does not.</p>
<p>Great designs come from great designers.</p>
<p>... very best designers produce structures that are faster, smaller, simpler, cleaner, and produced with less effort. ”</p>
