Some things are only capable of being done in space. Examples of that are looking at our Earth from that far away, and understanding the entire processes of storms and weather patterns, and oceans, and coastlines.
Decide that life is good and you are special. Decide to enjoy today. Decide that you will live life to the fullest now, no matter what. Trust that you will change what needs changing, but also decide that you're not going to put off enjoying life just because you don't have everything you want now. Steadfastly refuse to let anything steal your joy. Choose to be happy. . . and you will be.
