I did not direct my life. I didn't design it. I never made decisions. Things always came up and made them for me. That's what life is.

This quote is saying that life is unpredictable and things can change quickly. Rather than controlling and making decisions, life often presents us with circumstances and events we don’t anticipate, which can sometimes be out of our control. The speaker doesn’t feel they chose how their life turned out, but instead the events that happened simply unfolded and shaped their life.
