Did you ever notice that it seems like everyone wants the life they cannot have? I have had people envy me when I was single and not in a serious relationship and they wished they were.
I also see people who take their kids and spouses for granted, especially the kids. I see this, and wish I would have had children of my own. On the other hand, for a long time I didn't mind being single and not having that extra responsibility.
Another example is the rich people who seem to be so empty. I'm not sure if they would wish for a different life but many of them are suicidal, drug-addicted, and alcoholic even though they have all that money.
The list goes on and one. We all want the life we never had. I wonder how different my life would have been, for instance, if I had a second chance with my first boyfriend. Or maybe if I hadn't had people close to me hurt me in ways I don't even want to mention out loud.
The bottom line is we all have a destiny and we need to do our best to fulfill it. That is the best we can do-and live our life to the fullest even if it didn't turn out the way we hoped.
