We might also ask, Given my present situation, how long should I stay with uncomfortable feelings? This is
a good question, yet there is no right answer. We simply get accustomed to coming back to the present just as it is for a second, for a minute, for an hour—whatever is currently natural—without its becoming an endurance trial. Just pausing for two to three breaths is a perfect way to stay present. This is a good use of our life. Indeed, it is an excellent, joyful use of our life. Instead of getting better and better at avoiding, we can learn to accept the present moment as if we had invited it, and work with it instead of against it, making it our ally rather than our enemy.
