As the ancient greek epics such as the Oddesey, and the stories of Oedipus written by Homer, have told us time and time again that messing with fate ultimately will harm us in the end. I cannot say from experience if this is true or not, simply because I do not even attempt to change my feet (there is no need).
If you are trying to change your current life path, then do so! We have choices as human beings to live our life the way that makes us happy (or even sad, or perhaps angry). If you are unhappy with your life currently then change it!
Everyone deserves to be happy and proud of themselves. If there is fate for all of us, it will include some element of pride and happiness.
