You're just at "that age". I was burned out on milking cows at that age,just going through the motions. The wife was happy with her job,the kids were happy with their high school sports and social lives,I was just working everyday. But,finally,nine years ago after the kids were out of here,I sold the dairy cattle,the wife and I started to travel a little,had a social life again and it's the best time of my life.
The point is,yea,life sucks at your age,but hang in there,save a little money and things will be a whole lot better on down the road.
