Robert Frost and Modern day Language

I have a Geocaching adventure I am on and The poet I am sure is Robert Frost. (He is one of the very few poets I know that numbered there pieces of work.) But there was a little modern day thrown in here and now I am confused which poems they may be could you help me? Each line is a different poem

Here are the lines:

My eyes and heart made a promise to each other...
Extravagent beauty, who's gonna foot your bill...
Checkout the sunrise in the east...
Like a 2nd-rate bit player on the stage...
Those piddling goof-ups that happen when I'm free...
In forty years, when you get old...
I'm not like that one Poet...
Don't worry when I die...
It's OK if people say bad things about you...
