Is it possible that a chart may be too harmonious?

A person with only harmonious aspect is more lazy than productive. A person needs the squares to build character and overcome the obstacles. i always point this out in astrology that what follows the square aspect is the Trine. That is the reward following the square. The Trines are followed by oppositions. But unless you can compromise, the grand trines won't amount to much. Also, a chart needs a square aspect to one of the grand trine angle to release the positive energy. Otherwise, the energy goes around in circles and doesn't amount to anything. Harmonious aspect offer no difficulty.
