 If a problem is fixable, then there's no need to worry. If it's not fixable, then there's no help in worrying. There is no benefit in worrying whatsoever. Sometimes things seem uncertain, and you find yourself anxiously worrying about the future. Take a deep breath, repeat to yourself. There is no obstacle thrown my way that I won't be able to handle. Understand that you cannot be prepared for everything, and that things may not always go as planned. And that's okay.
