Passion and Initiative
Passion stimulates initiative. You have to start somewhere and since initiative must vanquish inertia, you had better have a reason to expend so much energy.
Alas, it is a lot like falling in Love: passion begets a broken heart. It took years to overcome my first heartbreak and years to heal from the pain of disillusionment the first time I was laid off. Sometimes, to avoid pain, we limit our ambitions in work and love, and we refrain from committing ourselves to opportunities to create something wonderful. But that only leads to more profoundly tragic disappointments.
I think that if you have the good fortune to find yourself passionate about something, then perhaps what you need to do is to cultivate initiative; Passion is the why and initiative is the what. When you fail in the pursuit of your passion, initiative can sustain you: when you lack the why, at least you still have the what. With a faith in your initiative and a mind open to new opportunities, you should sooner find the next thing that captures your passion, and you can fall in love anew, backed by the strengths gained from previous endeavors.
