If life isn't meant to be an adventure, then we should all know what our end goal is. Do you have a clear picture of your "end goal"? I don't. Maybe it's associated with a calling, but I'm not sure of my calling is either.
I think we all know what it's like to compare ourselves to others. Sometimes I can compare myself to people I believe have "direction" in life. I assume they've got everything figured out, they know their purpose and they know their "end goal". These people give the impression that they know where they're going.
The thing is, life gets swept up into planning. Everybody stresses out over getting the best opportunities, making as much money as possible, and finding our place in the world. We do all of this in the hopes of one day being successful. The problem is that we forget success isn't actually a goal. Success is relative.
Your idea of success might be completely different than the next guy's. So why do we all freak out when it's time to go to school and start a career? Does anyone really have a clue about what their single purpose of life is? I'm not talking about a hobby, a passion, or a natural ability. I'm talking about the ONE role that you're meant to play while being on earth. Does anyone really know what that is?
Thinking ahead isn't a bad thing, but I do think that some goals are just distractions. I think it can sometimes take away from the present moment.
It's okay to live life a little. It's okay if you don't know what you want to do with life. The process of finding that out shouldn't feel like a burden. It should be adventurous. It's designed to be that way.
