In my opinion the past  definitively has a major impact in the person's future. However, what happened in the past does not determine who someone may be, it does influence everyone's personalities but it is not all that counts.
Someone's personality is formed not only for what he or she has experienced in the past but also for external factors that may have an impact on them. A traumatic situation of the past may be hard to forget, nonetheless, it is not impossible. It is up to each one to allowed themselves to go over or get stuck in the past. It is also important to understand that we should not forget what we did, what we went through and where we come from because that is what keep our feet on the ground. We should not be living in the past, should not dwell of what happened but learn from it and beware of the lesson we received to build a better future and live the present. 
As Bob Marley said "in this bright future you can't forget your past" but we do not have to be attached to it. it is hard to find the balance. Because a lot people would "don't think about the past, forget about it" but the truth is that part of the person we are right is because our past experiences, as I said before, it does completely determine who you are but it does have an influence. People who went through a traumatic situation does not forget about it, but if they do heal their pain positive future things are more likely to happen to them.
So, in other words, it is not that you should keep thinking about the past but you should keep the lesson you learned.
