You need to take action and learn from the mistakes
Knowledge come only from experince.
What you mean is to get rich because for me being wealthy is having time and being rich is having money both need action procrastination is the enemy of progress we can liken it to riding a bike if you stop you will fall by continuing you regain your balance but before you start to take action you need to have a plan first then improvise as you go along, action without planning will get you nowhere.
If you want to get rich, set your clear plans to achieve your goal.
