Your life will probably never be what you pictured it would be - but that's actually a good thing. It may not feel that way, but it's a gift.
One of my favorite songs is called “Lazy Eye” by Silversun Pickups. I love it because I relate to it, in fact, I consider it my anthem. When I first started paying attention to the lyrics, I related to it because I was sad at the time. I especially related to the first lyrics when this phrase is sung: “I've been waiting. I've been waiting for this moment all my life. But it's not quite right.”
It's a simple concept - unfulfilled dreams. It hit pretty hard, and it was extremely difficult to face. I think a huge reason I felt this way is because of how I'm wired - I love dreaming about the future, I'm an INFP!
Now, when I hear those words, I can view it from a different perspective. If life were always how you imagined it would be, you'd be bored. Very bored. Maybe that's cheesy, but it's even economical. In the study of human action, you learn that we only research things like praxeology and epistemology because of the fact that the future is unpredictable. Time is a constraint, and it's a good thing that it is.
Find joy in dreaming big, but find even more joy in the process. That way, when things don't look “quite right”, it's just a part of the process - which you love anyway.
