Flannery O’Connor wrote: “Vocation implies limitation.” In other words, if you want to be good at something, there are other things that you have to give up. You can’t have it all, unless you want to be average or mediocre at everything you do. O’Connor wanted to be a great writer, so after morning Mass and breakfast, she spent the next three hours of every day, writing, with no interruptions. She said “no” to appointments, to visits, and even to reading before lunchtime, so that she could devote her entire self to writing, in order to become a great writer. It worked.
Limit yourself. You can neither be nor have everything.
