     The quality of patience goes a long way toward your goal of creating a more peaceful and loving

self. The more patient you are, the more accepting you will be of what life is, rather than insisting tha

t life be exactly as you would like it to be. Without patience, life is extremely frustrating. You are

easily annoyed, bothered, and irritated. Patience adds a dimension of ease and acceptance to your

life. It’s essential for inner peace. Becoming more patient involves opening your heart to the present

moment, even if you don’t like it. If you are stuck in a traffic jam, late for an appointment, being

patient would mean keeping yourself from building a mental snowball before your thinking get out

of hand and gently reminding yourself to relax. It might also be a good time to breathe as well as an

opportunity to remind yourself that, in the bigger scheme of things, being late is “small stuff”.

     Patience is a quality of heart that can be greatly enhanced with deliberate practice. An effective

way that I have found to deepen my own patience is to create actual practice periods-periods of time

that I set up in my mind to practice the art of patience. Life itself becomes a classroom, and the

curriculum is patience. You can start with as little as five minutes and build up your capacity for

patience over time. What you’ll discover is truly amazing. Your intention to be patient, especially

if you know it’s only for a short while, immediately strengthens your capacity for patience. Patience

is one of those special qualities where success feeds on itself. Once you reach little milestone(里程

碑)-five minutes of successful patience-you’ll begin to see that you do indeed have the capacity to

be patient, even for longer periods of time. Over time, you may even become a patient person.

     Being patient will help you to keep your perspective. You’ll see even a difficult situation, say your

present challenge, isn’t “life or death” but simply a minor obstacle that must be dealt with. Without

patience, the same scenario can become a major emergency complete with yelling, frustration, hurt

feelings, and high blood pressure.
