The best years of our lives to enjoy LIFE, is when we are young. Work overtime when you are 80 ;o)
I may disagree with this. If you can enjoy life in your 40s or even 50s (assuming your body keeps up) you appreciate and understand experiences MORE than when you were early 20s. Not to mention you have more money to spend than when you were young.
If you can retire mid 40s and your kids are getting out of college, no grandkids yet, THAT is a time to live it large!!!
