Best age to get married and have kids

I think that the best age to have children is at 27 or 29 years, when you are economically stable and when you are finished with your career.
If I were to marry I think I would like to do it at 24 or 25 years although it is a very difficult desicion. I personally believe that there is no time to do many things, like getting married and having children, but I do not even have a boyfriend and so far the idea of having children and getting married is very distant.
I think that in life there is time for everything, so we have to see what happens in the future.
