If you were determined to get enjoyment out of every moment, you would learn to do whatever it took. What it takes is not listening to negative thoughts, yours or anyone else's. Disregarding negative thoughts isn't hiding our head in the sand, but simply not allowing the negative to clutter and influence over our experience of the present moment. The moment is never improved or helped by negativity, although we are programmed to think our negative thoughts, worries, and fears serve a useful function. When you really examine this idea, however, you see that negativity doesn't serve. Focusing on negativity and fears doesn't make anyone a better person, nor does doing that help us function better in the world. In fact, the truth is quite the opposite.
