As my daughter so aptly expressed: The only person who can make you happy is yourself. There is deep meaning in this phrase and it is absolutely true. No matter what trials and travails you face in your life, it is up to you how these circumstances affect you. You can wallow in the mire and say "Poor me!" or you can look to the hope of a brighter future. As long as you keep looking forward and try to find the joy in the moment, you will have a good life with few regrets. It's easy to forget this when a tragedy strikes nearby, but it is essential for you to keep your head up and keep on going. Many songs and many poems have said this basic truth over and over again and we all, at times, seem to overlook it. We get so concerned with the bump in the road that we forget to see where the road is leading us.
I have always considered myself to be a "lucky" individual and much of this is due to looking for the good in each situation that confronts me. Life can be very interesting and the path you eventually wind up traveling isn't always the path you thought you were going to follow, but it brought you to here and you have choices from here on out which way to go.
