"Adversity reveals genius, prosperity conceals it." — Horace

Economic conditions in much of the world for the last decade have provided a surplus of opportunity.

Much of the credit is due to the ability to connect and trade with anyone on earth with an internet connection.

When economic circumstances change at the macro level, weakness is not created, it is simply revealed.

On one hand, "A rising tide lifts all ships", on the other — "You only find out who is swimming naked when the tide goes out." — Warren Buffett

To complete the metaphor, the tide represents the changing conditions of the market, and your ability to read the tide and adjust your behavior accordingly determines whether or not you get caught naked.
