Oh man. Delay, procrastination. It's such a demon.
Lose this day loitering, ’twill be the same story
To-morrow, and the next more dilatory;
True indecision brings its own delays,
And days are lost, lamenting over days.
Are you in earnest? Seize the very minute:
What you can do, or think you can, begin it;
Boldness has genius, power, and magic in it.
Only begin it, and the mind grows heated:
Begin it, and the work will be completed.
