Wise advice from Anna Goldfarb, in her New York Times piece "How to Be a More Patient Person", subtitled "Relax. It's going to be O.K." (5 Nov 2018, gift-link). Goldfarb cites three types of patience:

• Interpersonal — maintaining calm when dealing with someone who is upset, angry or being a pest
• Life hardships — finding the silver lining after a serious setback
• Daily hassles — suppressing annoyance at delays or anything irritating

To become more patient:

• Identify your trigger(s) — the "situations that set you off"
• Interrupt the cycle and evaluate the risk — "... take a step back from the situation and try to look at it as objectively as you can ..."
• Reframe the experience and connect it to a larger story — aka "cognitive reappraisal" – look for the good, "give grace to each other", "focus on why and how patience is integral to your values", and think "about how patience ties into your larger sense of integrity and poise"
• Train, don't try — work gently and gradually, seek incremental improvement, and make it a habit
• Consider lifestyle changes — reward yourself for small successes, add more time between appointments, cut back on caffeine, meditate, exercise, ...
• Be realistic — don't set impossible-to-achieve goals

And above all, be patient with yourself!
