Anything is hard to begin, whether it be taking a cold bath, writing a letter, clearing up a misunderstanding, or falling to on the day's work. Yet "a thing begun is half done." No matter how unpleasant a thing is to do, begin it and immediately it becomes less unpleasant. Form the excellent habit of making a start.

Lose the day loitering, 'twill be the same story
To-morrow, and the next more dilatory,
For indecision brings its own delays,
And days are lost lamenting o'er lost days.
Are you in earnest? Seize this very minute!
What you can do, or think you can, begin it!
Only engage, and then the mind grows heated;
Begin it, and the work will be completed.

Johann Wolfgang von Goethe.
