I know how you feel man. I’m 18 too and I want to get into a field that also has its risks. My parents were totally against it but I’m still going for it. They way I look at it: why waste our lives doing something we don’t like? Yeah, maybe it’ll be a bit harder to get a job and its scary but its something we love! When we are doing something we love, we are automatically more confident. We also tend to work a lot harder and excel greatly so we will go far. You just need to believe in yourself and know trust yourself. Fear is something we can’t run away from but fear is in our heads, it’s just a thought. The thought of failing…is just a thought. Not real. So just remove that thought and replace it with confidence. 🙂 sounds difficult but it can be done 😀 don’t doubt yourself and don’t over think it! Just trust in the universe and in yourself 🙂 things will work out.
