I completely understand what this means now more than ever. Especially since I don't necessarily agree with the notion that you should "make someone happy". I believe we are all responsible for making ourselves happy, our partners simply enhance that feeling by making us smile, making us laugh, making us feel ecstatic about something. But all of those things are just temporary emotions and they work both ways. They can also make you upset, angry, etc etc. The STATE of being happy is continuous and is internal and absolutely shouldn't be controlled by another person.
Be my peace (to me) simply means don't upset the upward trajectory that my happiness is ascending towards. Because, although the emotions a person might feel from that is temporary, it can throw a person off of that path enough to destroy it all. And that is enough to affect the state of being happy.
People focus better without distractions
