Can money be done? Yes the return can be from a collection that pays for itself to making an extra income, to doing this for a living.
Who are the people who can achieve those different levels?
Those that are passionate, know how to treat this like a business, know how to market themselves, know how to build a solid reputation, know the animals and their genetics (what to do what not to do) know the market, know how to evolve.
Who are those that fail?
Many of them! Those that have no clue, that think they are gonna make money overnight, that have no plan, that do not know & understand the market, that have to be spooned fed every step of the way, that fail to evolve with the market, that have no real passion, that have no patience.....
