There is a quote by Dan Custer that says this:
"Every morning is a fresh beginning. Every day is the world made new. Today is a new day. Today is my world made new. I have lived all my life up to this moment, to come to this day. This moment - this day - is as good as any moment in all eternity. I shall make of this day - each moment of this day - a heaven on earth. This is my day of opportunity."
So you can rewrite your sentence to say:
Because I think that EVERY morning IS a new start, so I feel like a new person.
