He’s not doing much with his life
Positive people are doing things! And it’s not because they succeeded on their first try at everything. It’s because they tried and tried again, until something worked out. If you’re a positive person something does work out. You’re working, you’re volunteering, you’re on a softball league—whatever. You like to fill your life with activities. If your guy isn’t up to much in his life, it’s because he doesn’t believe anything will make him happy or work out.
