fear later prudence
A quote about leaving things for later:
Later is where excuses live. Later is where good intentions go to die. Later is a broken back and a bent spirit. Later says “all-nighters are temporary until we’ve got this figured out.” Unlikely. Make the change now. – It Doesn’t Have to Be Crazy at Work, by Jason Fried, David Heinemeier Hansson.
A second quote:
‘To-morrow’: sometimes it is prudence; very often it is the adverb of the defeated. – The Way, n. 251, by St. Josemaría Escrivá.
