Easy money that came is easier to spend because you didn't worked hard with that. We don't know on his case but maybe he'll give importance to that money.
It's best to hear him out and how's doing nowadays.
So, that's why he needs a real advisor on his case, it might be whoever that knows the cycle of the company or someone who's really great with money.
Those who get money easily will of course find it very difficult to manage it well so for them of course they really need a financial advisor to be able to help them manage their finances well so they don't spend it on things they don't need because if they don't use a financial advisor with their money what they have, of course this will be very unfortunate because it is very difficult for some people to manage their money well and for those who have experience in managing their finances well, it will certainly be easier for them to manage their finances.
A person that have just received inheritance will certainly have hard time for it. But if his dad is too wise at all, he'd be welcomed to his company when he's still young and got taught on how the operations were done.
And then aside from that, he'd able to get some tips on how to spend money.
If not, then that's the best that he can do and that's to get a financial advisor.
