Who you are now is a result of who you were in the past; manifested in the present moment.
So the best way to change your future is to focus on who you want to be NOW.
That way, this moment becomes your new "past" as it goes by.
Not a total "makeover," per se. Maybe start with one small thing.
For example:
What's one quality that you want to embody now that will help you grow into the leader you want to become?
By the way, there's no need to hate on past-version of you. You did the best you could at the time. Give your past-self a hug for me, and then spend time being the you-of-tomorrow today.
