You have to wash laundry so you don't have to wear dirty clothes. You think "Pff I'll do it later." Your shirt smells bad the next day.
You have to walk the dog, but "One more round of this game." The dog shits on the carpet.
You have to prepare for a test in two days, but think "Nah, I'll do it tomorrow." You fail.
You have a slight headache, but believe "It's going away, watching this TV show is worth it." The next day you get no work done due to the headache.
You have a weekend you can use to visit your parents, but decide not to because "I can always drive by later." You never get to meet your father in person again.
