What would you do for free?

I’m constantly looking for inspiration from myself and others to clarify what I feel are important questions i’d like answers to in my life. One of these questions that i’ve recently been thinking about is…

“If you could do anything, What would you do for free?”

I asked my brother this and he said the best time he had was coaching kids Football (Soccer), other than that he’d make music. I often thought i’d be involved in sports myself (not as a gambler though), but as it is now i’m not sure what i’d answer to this question. If anyone knows of any links, advice, or their own ideas that might inspire me here, please comment, i’d appreciate it alot Thanks
