Advice that you wished you were given when younger.Lovely aged (50+ yrs) members of YA, what useful life advice would you give young people of today?
I'm only 49 but I just about fit the catagory. first there should be nothing on your mind but to do the best you can in school. you might think it's a waste of time but things today are harder to achieve with no high school diploma you can't even join the marines. stop making bad sexual mistakes save it for your marriages. men don't want a used women. teens are getting pregnant too soon. study and get good paying jobs before you start screwing up or live with mom and dad til your 50. I see so many kids screwing up jr. high. They'll regret later.Lovely aged (50+ yrs) members of YA, what useful life advice would you give young people of today?
