You either get into a business where others already have an edge or you don’t get into business at all. Even if you invent an entirely new field someone will still have a better network of investors and lawyers and all the other background aspects that apply to business in general than you and they will just see your new field and get involved with a huge advantage over you.
Go work for the best of the competitors you mentioned. Become their most valued employee and then either establish yourself as a partner or become competition once you’ve really got your chops.
Buy shit to rent out. Trucks, vans, trailers, construction equipment, recreational equipment like kayaks or rv’s and shit. Just think of things you or your friends and family may have rented in the last couple years.
No problem. Often I see people fixated on having a novel idea when really most successful businesses don’t really do anything that original. I run a masonry Contracting business. My field is one of the oldest there is. I certainly didn’t invent bricks or Scaffold or anything really. I see my job as just learning how to do things efficiently and finding the best possible contracts I can. You don’t need to reinvent the wheel, just use the wheel wisely.
