Do not be bored. Do what needs to be done. Do not fill up days with busying yourself until it is time to eat or sleep. This is sloth. Look around and figure out where you are most needed, what is most needed.
You are needed! Don’t doubt that, but it is not in that vague, feel-good way. You are needed and if you are bored there are at least two reason for it. You have time and energy, or you are not challenged. If either of these are the case then you need change.
Change your activity or lack thereof or change your purpose. Work is not a remedy. Work ought to be your life, your love. Your life is your work and if you are bored there is something wrong, and a way to change it.
It is up to you to do it; if nothing else change that fact. And to do something about it you must do what is needed. The very least thing we can do is to meet a need, ours or the need of someone else. The very worst thing we can do is to be bored.
