Proverbs 6 contains one of my memory verses to guard against laziness:

6 Go to the ant, O sluggard; consider her ways, and be wise. 7 Without having any chief, officer, or ruler, 8 she prepares her bread in summer and gathers her food in harvest. 9 How long will you lie there, O sluggard? When will you arise from your sleep? 10 A little sleep, a little slumber, a little folding of the hands to rest, 11 and poverty will come upon you like a robber, and want like an armed man.
