30 was very easy for me. I always thought people in their 30s to still be pretty young. Growing up in the 80s, most of my favorite musicians and actors, etc. were 30 and beyond....I never really had much respect for "art" from kids in their teens and 20s cause most of it sucked imo.
Now that I am approaching 40, I am debating that one more and more "am I still young??"
...but I still look and feel young and have recent pics to prove it
... so that is what matters most, I feel....if anyone is judging your age...how do you feel about yourself? usually it is on you face.

As far as goals.....What matters to me now is that I accomplish things that make me truly happy, not things that "a person is supposed to do by X age"....that is all BS, because everyone is different.
Set a goal to do what makes you happy and fulfilled. That is the ticket.
PS: Once you get in to your 30s...and start working more and more...the time really really flies. The past 10 years has vanished in the blink of an eye. Everyone older than me tells me that it gets worse and worse as you get older....so embrace the moment and live in the moment.
