It seems like you have a good understanding and knowledge about how to make money, but you need to create conditions so that other people need you to deliver money to you. I didn't find the best advice from you on how to make money more effectively, but everyone has their own best way to apply it in their life. Income productivity will make it easier for you to increase your wealth, but it needs to be adjusted to your expenses. You also need to adapt to technological developments to increase your income as many users do on this forum.
There's a point already on what he's referring to but with a poor delivery of the meaning he is trying to give to his audience. If it is with improving your finances, then to start things you need to identify what you have and what you want to achieve, I definitely agree with it. Seeking for growth is too broad; check on profitable skills to add with what's existing. Read books, articles, and free online courses which will give you additional stream of income then choose some that you will specialize afterwards then repeat the process. Another to consider is to have both savings and investments including emergency funds to make things consistent along your process of growing in all aspects. Of course these things won't be easily achieved and that when perseverance and dedication will be needed;it won't be enough to just idealize things, you need to act upon it. If you are seeking for growth be prepared to tackle sacrifices as well. These are the things I could advice in addition to OP's.
