Do not let cynicism impersonate sophistication.

Cynicism gets mistaken for insight because it is always partly right and never at risk of looking naive. But it is a stance rather than an analysis, and it costs you the ability to try things or to be moved by anything. Sophistication would mean judging each case on its merits.

Notice when your default response to something new is dismissal, and ask whether you have actual reasons. If not, consider taking it seriously for a while. Being hard to impress is not the same as being discerning.
