You'll just have to trust me on this--keeping several note/thank you cards in your glove box is a life changer. OK, that may be a stretch, but seriously, think of how often you wait idly in your car. Waiting to pick up your kid, waiting for the end of practice. Because when you build ten minutes of cushion time into all your appointments, you will easily find an extra five to write a simple note. Now you can let all of the people in your life know how much you care, without starting with “sorry this card is so late, but...”

Bonus points if you keep several stamps in your wallet!
