Whether you're 15 or 55, growing up is tough.
There are so many complicated nuances to navigating the world as an adult, and most of us weren't in the least bit prepared for them.
Even with the best parents and the most thoughtful temperament, you're going to hit some tough bumps in the road that you never could've foreseen.
Luckily, we don't have to learn everything through experience. Listening to the hard-won lessons of others is a great way to soak in more knowledge while forgoing some of the pain.

No matter how much you love someone you can't just make them love you, just as you can't make yourself love someone no matter how hard you may want to. And life is not fair.
