Ups and downs

When you live passionately, you experience all the ups and downs. The thing is: when you are up, you are high above the clouds, and when you are low, you are way down there in the pit of despair. Perhaps a middle ground would be the best. It seems logical, but... is this the way to go? I mean, I know successful people live this way as well, and I have lived like this at certain points in my life (I guess I sometimes get exhausted of that up and down wave). But I have learned a lot living in the wave, I have created many rich experiences and opportunities that others thought did not exist. There is no other way for me to live.
