Or maybe you've had a troubled marriage. Or it could be that you've experience a continuing series of career problems.
Troubles often come undeserved and at the most inopportune times.
Nearly everyone has, somewhere in their life, reasons to be angry, to be sad, or disappointed or disillusioned. And yet, the fact that life is unfair and full of difficulties is no reason to give in to those difficulties. Sure there are plenty of excuses for being less than you're capable of being. The troubles that life gives you have just as much power to push you forward as to hold you back. It all depends on what you decide to do with them.
