Why Resist?

Have you noticed a pattern in your life?.....that which we tend to be most resistive to ....end up being the most beneficial or fulfilling. I have noticed that pattern in the lives of others and at times remarked on it with a smile or a laugh. Now that I have lived a little more myself am seeing in my own life. So of course I have been thinking and wondering about this. Why in fact do we resist when in the end when we give in so to speak...we are the ones that benefit the most. So why then do fight that thing so much? Is it fear? Is it doubt? Is it timing? Is it control and our illusion of it?? Just a thought as the weekend comes to an end ....and the resistance of Monday creeps in....
