it really depends on the situation. if you are a toddler, there are not many things you can control because most of it is in your parents hands. as people grow older, they also become more independent, so they are able to control more aspects of their life. assuming that the prompt is talking about adults or young adults, i would say majority, like 80%. certain things, like our decisions, we have control over. however, we do not have complete control over the things that happen <em>because</em> of our decisions. when things don't go our way, we tend to blame it on ourselves, saying "this is all my fault" and "if i didn't do this in the beginning, this would not have happened." this is not necessarily always true. it could be that no matter what path you take from the first step, you were bound to get that result.
