Also, from personal experience people with those support networks almost always say 'And I did it all on my own!', though that's almost never the case.

They don't see borrowing money or using connections as a favor. I've also heard them say 'If I was born today to a broke family I'd still be rich by 30! I'm a hustler!'

These were my own family members and work colleagues, as well as an ex-girlfriend or two.
