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 someone wants to be rich, of course they need actions that they have to do and it is impossible for someone to become rich without doing something and for those who delay what they are doing, of course it is very difficult for them to become rich. Having a plan before taking action is the right thing to do. so that they can find out whether they will be able to carry out these actions well or not, because if they do something without having good knowledge and planning for the actions they take, of course what they do will not work well.
