Someone else will do it
There are times when we feel we should do something about the issues that we see around us, and then we tell ourselves "let someone else do it" or "someone else will do it" and then we move on. The day when we change our attitude from "let someone else do it" to "let me do it" or "why shouldn't I do it?" is when we will make real progress.
Whether someone else will do it or not is not in my control, but will I do it or not is fully in my control. Stop expecting others to do it and start doing it.
