Engage.

Lose this day loitering – ’twill be the same story
To-morrow – and the next more dilatory;
Each indecision brings its own delays,
And days are lost lamenting o’er lost days,
Are you in earnest? Sieze this very minute –
Boldness has genius, power and magic in it.
Only engage, and then the mind grows heated –
Begin it, and then the work will be completed!

Johann Wolfgang von Goethe
