Although this is a personal question that only you can answer, we can provide an example that can help you guide your work.
This question tells us that the world is constantly changing, and that in such a world, we are constantly required to alter our beliefs. Such a process requires us to also influence another's beliefs, ideally in a positive way. In a fair world, this process would mean that the best ideas would prevail, while the worst ones would be lost or ignored.
However, I believe that the world we live in is not one in which justice is blind. People do not tend to listen and take into account all people equally, which would be the just approach. Instead, people tend to judge ideas based on a variety of factors that can sometimes appear to be irrelevant. For example, people might judge an opinion based on the person who says it (looks, money, power, etc.) This means that justice is not blind when it comes to trying to positively influence another's beliefs.
