Thinking positively is a nice idea, but that doesn't change the situation; it is much better to evaluate your choices and do your part to make things better.
We make decisions all the time, and many are the result of our life experiences; we can learn from the outcomes of these choices and strive to make better ones.
It seems only fair that in a partnership both parties make an effort for its success; if you are only willing to consider your own wishes, can it ever be a true alliance?
Each day we should try to learn new things and be willing to consider actions; we may not need to change our opinions, but we should be increasing our understanding.
