Your environment would shape you. As hard as you try to resist it, you’d be influenced by it. If you’re surrounded by friends who smokes on a daily basis, there would be a high possibility that you’d pick up the habit as well.
However, you can use this to your advantage. Consciously surround yourself with people or a group who could help you achieve your goal. Need help losing weight? Join a gym, or an online forum with people talking about it. Get involved in communicating with other like-minded people. As much as we try to be alone at times, humans are social creatures. We have to interact.
Solid friendships provide needed validation that a person is valuable and of interest to other people. “Relationships help people feel that they’re worthy, that they are capable, that they can set goals and accomplish them, and that they can control their life,” says Toni Antonucci, a professor of psychology at the University of Michigan.
