Anyone can be a CEO… given enough drive, a growth mindset, and massive luck.
Drive - You must have some motivation to achieve what you want. Your drive can be intrinsic or extrinsic which is for you to sort out. Lazy people without drive will likely not achieve these big roles.
Growth Mindset - You must be able to adapt as your responsibility and situation change. You must always be optimistic as nobody likes following a pessimist. You will face a lifetime of learning and must never be complacent or lose your sense of agency.
Luck - There is of course a heavy element of luck involved. Not every venture you set out to do is going to succeed, so opportunity can be a numbers game. For every “successful” leader, there are hundreds who are not.
