One can always find the courage to work through one more day—to endure hardship, pain, discomfort or merely inconvenience for the sake of progress.
Remember, nothing can be built without sacrifice. It is therefore your duty to use your Reason to determine how to both minimize your pain and maximize your gains.
You must do this without interfering with the rights of others. We must all be allowed to live as Reason allows.
Build a legacy while doing no harm.
That is the challenge I have seen few succeed in accomplishing.
