E. Nesbit: "That is the way to learn the most: when you are doing something with such enjoyment that you don't notice the time passes."

Don’t let your happiness depend on something you may lose.

You thought you were here to get stuff, prove yourself, and find people to love you. Instead you are here get peace, be yourself, and find people to love. You thought you were here to fix the world. Instead you are here to appreciate what is before you and see the world through new eyes.

If they don't respect, appreciate and value you, then they don't deserve you.
