I want to express the idea that:
If you want to be rich, you have to have guts and take a big risk.
If you want to achieve a high position in your society, like becoming a doctor or lawyer, you need to have a strong will (strong will is enough, not necessarily taking risk).
Does "fortune favors the bold; cheek brings success" express those two ideas?
Is it a popular idiom in English?
If not, what is another way to express those two ideas?
