This may seem like an overly simple piece of advice, but it’s something you can use in just about every situation in life. If you don’t believe in God, think of it this way: Trust those who are trustworthy, and be cautious anyway.
A lot of us are too casual with our trust, and some are too stingy with it. In order to pursue success in any endeavor, you’re going to have to exercise a little or a lot of trust. You may have to trust yourself, you might have to extend some trust to others from time to time, and yet each time you do presents a risk. It’s good to be positive, upbeat, and optimistic, but be prepared for risks and their possible consequences. Not being prepared can make an apparent failure seem worse than it is, and can then influence your attitude in behavior in a negative way, which will increase your likelihood of negative outcomes.
Then what are we to do? Lock that car. Take necessary precautions. Do what you need to do to be prepared for the worst, and then take action in good faith.
