Space - I am 24 and I don't consider myself ready at all! I have already seen many of my friends get married AND divorced. Coming from a divorced home (my mom has been remarried once and my dad is on his third marriage) - marriage scares the crap out of me!

Also, I think nobody is really ever 'ready' for any of those. If you are not scared - I think THAT is when it's not normal. These things are life changing decisions which should always be a least a little scary.

Who knows.....if you meet a really awesome person who just sweeps you off your feet you may feel very 'ready'. Don't beat yourself up over it though.
