Is it worth it working for free? FYI I'm 16

[David Kovalchuk]

Hello, my name is David, I'm 16 and I want to become a real estate developer when I'm older. It's a very long road ahead and I know that. Recently I've been looking for jobs, I've been asking around my community but nothing's working. I've asked pretty much everyone I know who has anything to do with property development, property management, you name it. I personally value experience over money and I'm willing to work for free but is it worth it? I've thought about going door to door and starting a window washing business but I don't want to do that simply because I don't get experience. Sure, I may get some negotiation experience but I'd rather have work experience. Also, any other general tips are accepted. I take any advice from anyone.
