Musar sobre Êxodo 5:13

Complete your daily assignments as every day!" (Exodus 5,13). We learn that even here, when making bricks, no allowance was made for any shortfall ever. When someone has wasted time instead of serving the Lord, he cannot make up for it by saying he will henceforth serve G–d by day and by night. He should have done so in the first place. Waste is something that cannot be compensated for.
