Some circumstances can be controlled, but others may occur without any opportunity to change them. Often people take credit when something goes right, but when things fail the circumstances are commonly blamed instead of the individual taking personal responsibility. No matter what circumstances you find yourself in how you react will reveal your true character as a person.
Spend life with people who make you happy, not those you have to impress.
The problem is not the problem; the problem is your attitude about the problem.
