You should let them discover your hidden treasures, just as I have done. For instance, were you to set out to impress me, you would come across as a nice guy who just happens to have a graduate degree in technology and who holds or shares a patent or two. Maybe first you'd let me know about your hard-rock mining experience or your career as a seaman. Bit eventually the Awful Truth would come out: you play banjo. This would not lower you one whit in my estimation, but it would excite my pity that such talent wasn't used for God's Own Instrument, the trumpet.
