However for the case of people earning salaries, do you think there is a way they can be really rich without owning a business and or is it compulsory for one to be own his own business
I learnt from some business Moguls that you need to invest back to the business, it could from a 50% range upward but it's needed to invest back to the business that way you give room for more growths and when need be you can still fall back to it . So in handling a business this should be considered that way you can take your business to the next level but a business owner without investment is empty.
if the business you are doing is yielding some good returns, it is just natural that you invest back into it so you can get more returns from it. it takes mony to earn mormoney and that is the brain behind the sucess of most business. some will try to diversify their profit into some other business so hey do not keep all their eggs in one basket but then, there is still a level of risk in such a methord because chances are high that the new business you are considering might not do too well. concentrating on a business you have seen to be yielding you good profit is one good way of creating wealth.
it is same reason why we always advice that if you are investing in bitcoin, just stay invested in it and do not try to diversify into things you are not sure of it returns in he next couple of years to come. by being all soaked into bitcoin and adding more and more to your bitcoin stack, you are going to easily create good wealth that will stand the test of time for yourself.
