Every single time I forget this, I live to regret this. From the simplest of situations to the big life situations, the best course of action is to start doing the things you think you want to be doing at the end of the situation. You need to spend time thinking ahead to what the future might look like before you begin.

Current example: my dog loves popcorn. I used to share with her when I made some yummy, buttery popcorn when watching a movie or marking exams. Several years on, she is a crazed lunatic for popcorn. In fact, I rarely make popcorn because of the hassle of eating it with her face two centimeters from my popcorn bowl or whining under the table.
