That beauty is everywhere, even in places that you don't think it even exists in. You just have to look deep and hard to find it. Whether it be in a person, a place, art, sound, nature, happiness, sadness, love, a chance meeting, a thought... It's there. Beauty comes in so many different forms that is not only restricted to physical appearances. The earth that we live on is covered with beauty, but often times, it is overlooked or goes unappreciated.
That you can't expect anything. You can't expect for everyone to like you, you can't expect to get discovered and become famous, you can't expect to be rewarded and treated good by everyone even though you deserve it. No expectaions. The saddest yet most important rule that exsists.
