If something is important enough to you that you feel the urge to donate your money or time to it, I think it's best to try to express that form of giving through your career, not just as something you do on the side. If you enjoy your volunteering and charitable activities more than your career, it means your career is in serious need of an upgrade. In my opinion your career should be your best outlet for giving.

I believe we can proactively choose to believe whatever we want instead of merely letting our beliefs coalesce as reactions to events.

Embrace opportunities with limited downside, unlimited upside. The best deals are those where your risk of loss is predictable and fixed if things go wrong, while your potential gains are enormous if things go right. Take such deals whenever you can get them if the odds of success are halfway decent.

Regardless of others' reactions, do your best to stay true to yourself. Make the choices that allow you to look in the mirror and feel good about the person gazing back at you.

Courageous people are still afraid, but they don't let the fear paralyze them.

Replace "Have to" with "Want to."

If you really believe something, you will act in accordance with that belief - always. If you believe in gravity, you will never attempt to defy it. If you claim to hold a belief but act incongruently, then you don't actually believe it. You're only kidding yourself. Casual faith isn't.
