Yes, it's a common quote. There is a reason why they came with this quote. We were supposed to see things that weren't there. It's pretty simple if you think about it. For example, how many times have we been burdened? Sorry, silly question (just wanted to remind us all).
Commitments. In "Up In the Air", George Clooney said, "Put all those things or commitments into a backpack. Now carry the backpack on your shoulders. How does that feel?" Now, imagine yourself being told to do so. Kinda "heavy" isn't it? Basically, guys, what do we do when we feel that burden? So, read between the lines.
Folks, there is no secret, there is not one single thing you can do to avoid anything burdening you. There is no SECRET. Sure, you've heard about this before. Pretty cliche stuff, I suppose. Ask yourself, "What do I do?" Great, you're starting to see. Now, for me, it's all too common to feel weighted, even by the simplest of things. Depressing, I feel. And I'm pretty sure I'm no different than anyone else. Just as Tom Hanks was once told by his mother in Forest Gump, "You are no different than anyone else," .
There is a meaning. I know that, you know everybody knows that. Now, lets widen our imagination, what do you see about your commitments in the future? Clouded, no doubt, but nevertheless, beautiful, I hope. Simply, keep an open mind, see what you can't at first, and then realize. Go past that mental block, and well.. just feel it.
