Advice to become millionaire in O&G

Any millionaires want to give some of the younger guys some advice? I hear things like get into scada go to midland, get into engineering/management go to Houston. Invest into 401k and other things. I see and hear about but never had a conversation with somebody who actually did it. I'm a open book willing to learn and I'm sure others would enjoy it as well. What did you do to become successful career wise? Or if it was investments maybe give some insight to it without ruining your game

Thank you for your time all
