Courage is not never being afraid. Courage is having fear and acting anyways.
We are all fearful of something – being criticized, looking dumb, losing a loved one, losing our health, losing our status/reputation, losing our job/career/income, etc. But the only way to live life is to hear your fears, but to keep pushing forward.
Don’t let your fears stop you from taking action. Use them to motivate you to make your life better.
