9. They don’t believe everything they see in ads. Many advertisements are designed to make you feel lacking. Companies that want to sell you products usually start by making you feel bad about yourself, often by introducing a “problem” with your body that you would never have noticed otherwise.
10. They don’t believe everything they see on social media. This point is closely tied to #9. It’s easy to believe that everyone around you has the perfect marriage, a dream career, and supermodel looks to boot. But remember that what people post online is heavily curated and edited. Everyone has bad days, self-doubt and physical imperfections. They just don’t trot them out on Facebook!
11. They don’t avoid trying new things. As you keep pushing yourself to try new things, you’ll start to truly understand how failure and mistakes lead to growth. An acceptance that failure is part of life will start to take root. Paradoxically, by being more willing to fail, you’ll actually succeed more—because you’re not waiting for everything to be 100 percent perfect before you act. Taking more shots will mean making more of them.
