Always be ready to survive alone. Not because people will leave, but because you need to know that you can stand on your own. Depending on others is easy. But what happens when they're not there? Learn to be your own support system. Learn to find happiness within yourself. Learn to be okay with your own company. Because the strongest version of you is the one who doesn't need anyone but chooses to have people around. So don't fear being alone. Embrace it. Grow from it. Become someone who is complete on their own, and then let others add to your life, not complete it.
