Acknowledge what you can’t control
Accept the things you can’t control, and use that energy toward changing the things you can. You have no say over traffic, your boss’s mood, or the economy, so don’t let them control your own happiness. Make a list of the uncontrollable things in your life, and post it on your fridge or computer. Then when those troubles arise, focus on reacting to them with patience and levelheadedness.
Self-assess the changes you can make
Whenever you find yourself in a tight place, describe what you would have done differently in a journal. For example, you get reprimanded at work, don’t beat yourself up for it, but do acknowledge that it’s not necessarily because of bad luck or a mean boss. Ask yourself what went wrong, and whether keeping better track of deadlines or researching more thoroughly could prevent a similar future mistake.
