The Fremen were supreme in that quality the ancients called “spannungsbogen” — which is the self-imposed delay between desire for a thing and the act of reaching out to grasp that thing. — The Wisdom of Muad’Dib

My Take – I never fail to fail when I impulsively get what I want.  I have three rather expensive pieces of wood and metal in a safe downstairs that I bought on a whim and now don’t take out very often, either because they’re expensive to feed or are unreliable.  I have an ex-wife because I wasn’t willing to wait for our relationship to properly mature before we ran looking for a justice of the peace.  Both of us came to regret that, and our regret had repercussions for many other people, including our child.  If something is worth having, it’s worth taking the time to make sure it’s what you really want or need and not just something shiny that fascinates you for the moment.
