The best preparation for good work tomorrow is to do good work today.
Nothing ever comes to one; that is worth having; except as a result of hard work.
Nothing will work unless you do.
Opportunity is missed by most people because it is dressed in overalls and looks like work.
Everyone has been made for some particular work; and the desire for that work has been put in every heart.
Always do your best. What you plant now; you will harvest later.
Ralph Waldo Emerson
