What Thing Seemed Unimportant At First But Changed Your Life Forever?

In the long run, some things turn out to be incredibly significant to our lives, even though we couldn't have known about it at first. For example, when I was a little kid and still couldn't swim, my father had to cut the grass around the pond in our back yard. He was planning to do it early Saturday morning, but his friend dropped by for an unexpected visit and the two went fishing, so my pops postponed cutting the grass to Sunday. During the same Saturday, I was playing on the high edge of the pond and overextended a bit, falling into the water. I didn't know how to swim and the depth was well over my height so I began just instinctively reaching for anything around me I could get a grip on. Long story short, I climbed out of the pond by gripping the grass my father had to cut down. Remembering that epic day I can't help but wonder - what things in other people's lives seemed unimportant at first but changed them forever?
