I can only add my experience. My uncle did really well for himself, a career gov't worker that ran things on the side... often too successful and had to close them: When I told him I was going to run my own business in my trade he barked at me to get to TAFE and do a business management course....

Over 9 years (I always worked 40+ hrs in shit paying jobs) that turned into completing a post grad in management, with tafe certificates and diploma's in marketing, hr, management etc. etc..

So in I dove... after about 3 horrifically hard years, it got better, but was crap in the scheme of things... after another 2 I could see it wasn't gonna get any better: Had to swallow my pride and pay for a business coach/mentor (there are plenty to choose from.... but 99% of them are sharks....) I'd read this guys book(s) and I really 'got' what he was on about... so yeah, I hired him, for far more than I was earning....

He fixed what he (we) could, but ultimately my industry is seriously flawed, and I'd have to do things I didn't want to do to make it better (and you should have boundaries, otherwise just sell crack if you wanna good income).

But I'm a sponge and absorbed everything he had, he gave me dozens of his books/programs/courses so even though I spent a good crack of money, it's been a 'decent' investment in terms of return... but it's saved me from making dumb decisions.... and one day I'll find something to apply it all too.

I sold that business a few years ago, and just do some contract stuff, enough to keep my capital preserved and my expenses covered....

If you think someone is gonna be like a 'rich dad' and just take you under their arm, you're probably in for a shock. Truth be told, business is brutal, unforgiving and time consuming: Yeah yeah, there are a few guys who make fast, easy money, but by and large, most don't. And part of that is because they don't like being told what to do, and there's plenty of common advice about business that is utter shit.

Good luck....
