Bits and pieces of what I am

I don't know if I can keep up.
I just wish for your hand to hold on to.

It was all about you.
But I do hope it'll be all about me once in a while.

Time is passing by so fast, don't go with it.

I will try no matter what. I don't want to give up again.

To understand and to do something about it are two separate matters.
I guess you understand.
But it stops right there.
