new beginnings

I wonder if there is a limit on how many new beginnings and/or second chances a person can have in their lifetime. At what point does one cross the line? Is there a line? I like to think that no such boundary exists, and that life is a process and sometimes as much as we leap forward we often takes steps backward.
My life has been a series of steps/stages, some good and some not so pleasant...I've been through a lot, made a few too many mistakes, and hurt some very great people.  However, in retrospect, those bad" times have also brought me many great things. Suffering is a part of life, and we all fall down sometimes. Everyday i am surprised and amazed at the strength human beings possess to rise from the deepest and darkest turmoils of the soul and reclaim their precious lives.
I've been to the darkest corners of my being and back again many times over, but yet somehow i have managed to find the light. Depression plagues me and I've battled anorexia ...but i have no regrets. Life breaks you down so you build yourself back up. By putting my mind,body, and soul back into place ive truly learned who i am, where i've come from, and where i am going. No single person is perfect. We are all made in the shadows of imperfection..but in a sense that is what is so entirely perfect about the matter.
