Trying to be a Nomad

I want to take a year simply exploring the world. I have no budget as you guys know. But if I were to go home, I think I can afford it. Even better, I might have enough to start a company. I can live off my grandparents’ farm. But I have a math problem. For sure, I can leave for 2 months but I might need to come back to my city right now for a week or two for a professional event. Should I airbnb my room out? or should I just completely get out of my lease?
