I saw a poster in a school gymnasium with the words “good things happen to people who try.”
Of course, good (and bad) things happen to people at every level of the trying continuum, so that is hardly saying anything.
One could interpret the poster less literally as: “good things happen at a higher rate to people who try compared to people who don’t try.” However, that is a non-interventional statement, and hardly motivating. (i.e., people who try might be different than people who don’t try in many ways, and it is those ways, and not the trying, that causes good things to happen to those people at a higher rate)
So, we can fix the interpretation a little more: “if you change from not trying to trying, good things are more likely to happen to you.” But that implies that the thing you are trying to accomplish, the thing that can be aided with effort, is a good thing. Because certainly someone who is self-destructive could try harder to self-harm. Similarly, sometimes we want to accomplish things that we think are good, but are really not.
So, my proposed revised poster: “achieving specific goals is more likely to happen if you increase your level of effort; whether or not that is a good thing depends on the degree to which you select goals that are good for you”
