When you encounter a new idea, the influence is often brutal. It takes possession of your whole system, and violent reactions sometimes follow. You're greatly agitated, and you think about the idea the whole time.
Gradually, the novelty is lost, and the idea is incorporated into you. The explicit encounter turns into implicit knowledge. The idea becomes part of you, and you need not think about it all the time. More often than not, you forget the idea itself.
As we approach the springtime in the northern hemisphere, I sometimes think if we should not regain the initial agitation from time to time. The excitement as you discover a new idea, which changes your life, and burns your heart. Although such a reaction is often short-lived, it is one of the primes of our life, and it is well to remember. Spring is a fit season for the resurgence of young and bold in spirit.
