The age cycle - let's be wealthy

Hey, everyone, hope everything is all good. I heard about this age thing, that say those young people up to 20-year-old, is a happy people because they are most the time very innocent, don't have big problems, do not work, do not have many responsibilities, they want to live they live with no compromisse, etc.
The people between 20 and 50 are the most unhappy people that you can think about. They get married so is one more person in their lives, they have kids and not always on the time they planed or want, they have to work, buy a house, carrying a mortgage, work even more for a better and bigger car, stress they selves so much that they can not go on vacation for about 10 years, taking care of elderly parents, kids in school and they can not go to play their hobbies or relax on chairs for hours on they favor beach; wow, this is really exhausting.
The happiest people are the ones over 70s, because most the time they already are married for a long time, has paid in full the mortgage, don't have any more car payments, don't have to respond to a boss anymore because they are retired, kids are out of the house, they can take vacations every year, go to a restaurant about 3 times a month (senior meals is a good meal for a good price), anyway, they so far have build they wealthy that brings freedom, lifestyle, peace.
We are here at WA, working very hard, to be like these people after 70s, but with a young age, we are here to build this wealthy as well; I am not talking about money only, because been wealthy do not mean be rich with material things, means been secure, stable, with time in your hands to joy life, been healthy as well (very important), helping others in need, make the difference...
Let's continue our journey working hard, going through our training, be persistent, be constant and most of all be patient. Let's enjoy our age cycle with wealthy.
At this moment, I am just under which category would be the people on the 60s? What do you think?
Thank you for reading my blog.
I think every age group has its wealth. The yougest we have the wealth of discovery, new chalenges, becoming parents for the first time, falling in love for the first time ...
The older ones are the age of the wisdom and discover another serenity that we have not younger and they take the time to teach to their grandchildren what they don't know yet.
Whether we are young or old we are all rich in our own way.
WA as you say so well will bring us the serenity we would have had later.
Thanks for your great post!
