Tomorrow
Sir Walter scott was an accomplished writer, a poet, historian and biographer.
When he died in 1832, the last words found in his diary were: "Tomorrow we shall...." But there was no tomorrow for him. He died with good intentions to accomplish a certain goal - a goal that was neither stated in his diary nor accomplished by him.
Every person has goals and dreams that he or she longs for, plans for and even begins to reach for, yet there are many people who fall short of their goals simply because of limited time or opportunity.
That is why it is always important to get busy and do the right thing at the right time. Never delay that which needs to be done today, for tomorrow may never come. source.
