You can never become what you aspire to be if you allow yourself to think in negative terms. It is not enough to refrain from having negative thoughts. More than that, you need to be able to view everything that you come across in a positive lens. It is not something that anyone can just do. But it is very possible for anyone to get there. What is needed is a choice. Your choice. You could let the irresistible allure of the negative energy to consume you especially when things do not go your way or you could put an end to victimhood and reclaim your life force by making a conscious decision to choose to think in positive terms. There is always something positive in every single situation. If for some reason, you are unable to find it then believe with all your might that it will manifest or come to realisation in the future.
