At the start of a day / project / interview / date / etc. Do this one simple thing: State your intention. How do you want to carry yourself? What is the goal for the outcome? Just take a moment to imagine how you want to behave, react, appear, etc. What impression do you want to leave with the people you interact with? Of those things that are in your control, what outcome would make you proud?
There will be many times in your life you feel powerless. What makes you feel powerful? For me, it's a good run, listening to good music with the volume on high. Prayer reminds me I'm connected to God, who is powerful beyond all measure.
Depression can look a lot like a bad attitude. Try reacting to his chronic edginess with “Sounds like you’re in pain. You can come to me about anything, any time.”
Staying calm while under pressure or when you could scream in frustration - that is most of the battle. Sometimes the fact that you stayed calm qualifies as a win.
Work on developing a “no shortcuts” mode. Looking for a faster/easier/bare-minimum option isn’t always bad. People get paid a lot of money for creating efficacy. But there are times when that approach is wrong. Anything you want to grow from (relationships, school, work, wealth, health, knowledge, etc.) those things deserve your full effort, focus and dedication. Play. Definitely play! But don’t f*ck around.
Try to avoid the temptation to reach a conclusion too quickly or cling to it too tightly.” (Paraphrasing James Comey from his book ’A Higher Loyalty,’ which I recommend as a fantastic lesson in leadership - and history, and public service.)
The next world is perfect and permanent. This world is neither, so save yourself the stress of trying to make things perfect (house, job, body, relationships, bank account, etc.) Embrace the impermanence by cherishing the good times. Know that the bad times won’t last. Remember that you are loved very much, and that God will shower you with the grace you need to handle whatever this imperfect life throws at you.
