How do I start racing with no money?

How do you embark on a racing career when you're short on funds? Is there a way to compete without breaking the bank? Perhaps there are sponsorships or grants available for aspiring racers with limited resources. Could you start small, by participating in local events or joining a racing club, and gradually work your way up to more expensive competitions? Or is it essential to have a significant financial investment from the very beginning? I'm curious to know if you have any advice for someone who wants to race but lacks the necessary funds.
