If you aren't content with where you are, leave. If it doesn't feel like home, they aren't your person. If you constantly crib about how tough life is, look around often. If you believe that love was always meant to be unrequited, think about the people who loved you, but you couldn't love them back.
We are often clouded with this idea that our wants are unlimited. Yes, there is a word for it- Desire. Humans are fueled by this unreasonable idea of 'limitless wanting' to an extent, that they start believing it. When we want something and later get it, we want more. Desires don't increase. We just tend to want something new, something different. Humans tend to achieve a false sense of accomplishment by trying to obtain what they don't have. The tougher the battle, the better the rush.
We cling on to false hopes, we seek pleasure in misery. Now that's not your life battle; that's your struggle with self. You and I have read enough spiritual books that tell us how our problems are self inflicted and have no connect with what our lives could have been, had we attracted positive things. Nah, I don't want a good life. I only like the bad boys.
