We often exclaim, "I'm so tired!", and then continue on to complain. But we should be careful not to make a habit of complaining. Everything is the result of our own choices. Though some say they do not have a choice, there will in fact always be more than one road to go down, even if one of those roads represents giving up. Not choosing itself is also a choice. Therefore, since everything is our own choice, we should shoulder our responsibilities and face them with a smile.
