In thinking deeper on this subject my answer is no. As we move through life we are a product of our experiences and thoughts, some positive, some negative, and some just downright misconstrued.
New beginnings, starting over, it's more of a renewing of the mind than an actual rebirth. All of us need to adjust our thinking by pushing the positive forward, negative back, and finding the truth. Changing our thinking first and following with changed behaviors. Which leads us to another question...whose to say what is positive or negative for a person, where is the benchmark, who makes the rules, what is the truth?
That too depends on your belief system, many people believe in something bigger than themselves, at least it is my hope they do. I am a Christian, so my "benchmark" for right and wrong, positive and negative is scripture. Not that I don't fail miserably most days, I do, I'm human, but I know the standard and the goal.
Renew your mind through your faith.
By renewing my mind through my faith, I can be assured that each day is a new beginning. Not just Jan. 1 New Years Day, or the beginning of a school year, or the first day on the new job, but each and every morning. Relying not on ourselves but on the word of God will give us a clear direction and perspective enabling us to rise each morning and treat it like a "new beginning."
Lamentations 3: 22-23 22Because of the Lord’s great love we are not consumed, for his compassions never fail. 23They are new every morning; great is your faithfulness.
Romans 12: 1-2 1Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. 2Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.
