We convince ourselves that life will be better after we get married, have a baby, then another. Then we get frustrated that the kids aren't old enough and we'll be more content when they are. After that, we're frustrated that we have teenagers to deal with... We will certainly be happy when they're out of that stage.
We tell ourselves that our life will be better, more complete, when our spouse gets their act together, when we get a nicer car, are able to go on a real vacation, when we retire. The truth is, there's no better time to be happy than right now. If not now, when?
Your life will always be filled with challenges. It's best to admit this to yourself. Know this and decide to be happy anyway. One of my favorite quotes comes from Alfred D. Souza. He said, "For a long time, it had seemed to me that life was always about to begin--real life. But there was always some obstacle in the way, something to get through, time to be served, some unfinished business, a debt to be paid. Only then, would life begin. At last it dawned on me, that these obstacles were my life."
This perspective has helped me to see that there is no way to happiness. Happiness is the way. So, treasure every moment that you have and treasure it more because you shared it with someone special, special enough to share your time with and remember that time waits for no one...
Stop waiting until you're finished with school, until you go back to school, until you lose ten pounds, until you gain ten pounds, until you have kids, until your kids leave the house, until you start work, until you retire, until you get married, until you get divorced, until you get a new home or a new car or until your car and home are paid for, until spring, until summer, until fall, until winter, until the first or the fifteenth, until your song comes on, until you've had a drink, until you've sobered up, until you die, until you are born again to decide that there is no better time than right now to be happy.
Happiness is a journey, not a destination. And so it is said, Work like you don't need the money, love like you've never been hurt, and dance like no one's watching.
