I can be changed by what happens to me, but I refuse to be reduced by it.
Say that to yourself every time you face adversary.
For the one thing that’s certain for us all is that we will all change as we grow (change is ironically the one constant thing). But that doesn’t mean that change is bad. In fact, all obstacles in your way have the potential to either reduce you or increase you. But you have to stand your ground and push forward with your will if you want the latter.
Refuse to be reduced. Aim to be increased.
