"Be practical as well as generous in your ideals. Keep your eyes on the stars, but remember to keep your feet on the ground."
I really relate to Teddy Roosevelt's quote here and wish more people would to. I'm sure you know people who dream of having a mansion. Why not just a nice house? They dream of driving that sports car, when a modest sedan would do fine as well. A lot of men think about marrying that beautiful super-model, and will reject plenty of decent women in the process. Why do we as humans think we are some kind of divine royalty? It's not a bad thing to want nice stuff, but don't expect things beyond reason or you'll have a hard fall to reality.
