I understand what you say and I assume you have more experience than me in this field.
But even if you fail, that's experience too. If you have a dream, I strongly encourage you to pursue it. It is usually more painful to look back in hindsight and one day wake up to a reality where you never even tried.
To whoever is reading this: Try. Then try again. Then try another. And don't forget to look after yourself and your loved ones.
