Life
I just wonder why all of lifes challenges arise, but more, why they are so difficult to make decisions for. The most interesting things come up at the most inopportune times (or visa versa). There are usually positives and negatives to each side, which is where the confusion comes from, the uncertainty of the decision you're faced with.
There's no book you can read, no person you can listen, because you aren't that person and that person is not you.
Asking opinions may or may not be helpful, but it doesn't give your answer. Your friend, your brother, your boyfriend other otherwise can't tell you what is right. Your answer is only for you to figure out.
Either way, you will learn something, though either way you are taking a risk.
On a lighter note, watch this..
