We will certainly be happy when they are 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 is no better time to be happy than right now. If not now, when? Your life will always be filled with challenges. It is best to admit this to yourself. Know this and decide to be happy anyway.
Quoting Alfred D. Souza, "For a long time, it had seemed to me that life was always about to begin-real life. However, 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 helped me to see that in this life, 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 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 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. Therefore, it is said, work as if you do not need the money, love as if you have never been hurt and dance like no one is watching.
