Why does this goal seem so easy.. but then when I start really thinking about it, it’s the most difficult thing ever?!

I’m pretty sure I’m still too mentally young to decide this. My mind latches on to every little thing I even mildly enjoy.
I was set on Pharmacy for a while. Now I realize I would never do that.
Then it was Photography. I still love photography (wow.. something that lasted more than a year (5 to be exact)) but I realized that there’s no way to make a living off of photography alone.
During my Economics class… Yep, I wanted to do something with Economics, namely stocks. I even signed up to take Microeconomics next year in college.. Now I’m thinking that was a mistake, but I don’t know what to switch it to.
I guess I’m kinda now thinking that I’ll major in business and then take whatever comes my way after that.
And then a part of me just wants to travel.

This is such a horrible situation to be in.
