Why

[Pelin]

@Andre Taking action is always necessary, but what I got from your question was action regarding changes.You're right, the possibilities turned into musts for me sometimes, but not all the time. Don't underestimate my third point   Changes are difficult, it takes putting your heart out there. But trust your intuition. If the change is about to happen you will embrace it with passion and less fear

True, how would you go about creating the desire to realize something? 

I never found 'a reason' to do anything  My search for motivation ended in vain; Through intellect, I never found 'justification'.
Yet, I still feel an urge to realize my potential, become that which I can become. And so I do, just because that is what I happen to intent.

To change the course of your life, choose one of two basic methods: 1. You can direct your energy and attention toward trying to fix your mind, find your focus, affirm your power, free your emotions, and visualize positive outcomes so that you can finally develop the confidence to display the courage to discover the determination to make the commitment to feel sufficiently motivated to do what it is you need to do. 2. Or you can just do it. -Dan Millman

However, resistance is still very real. You should read 'The Path of Least Resistance'. It is the best book on creativity, or motivational frameworks, that I have ever read. Seek to gather principles for how to more effectively create that which you intent to create.
