Anything you put efforts in to generate wealth is your own investment it doesn't necessarily mean that you should invest money to make more money in the future but getting ideas that could generate money to you is the highest form of investment and it could make you become wealthy if you use your ideas to create things that would attract people to come to you and if you can solve their problems with your ideas you will also become wealthy.
I think that it's important for an investor to understand that anything that we do, with efforts that put into our assets or portfolios or skills, it's a kind of investment that will make us earn money. And from there, it will depend on how we're going to capitalize that profit we make from there. If we're going to put it back to our craft or put it into any investment like Bitcoin, that's the kind of cycle that a skilled person does if they want to become wealthy. While having ideas are good, it's not enough to have that only because it has to be executed and done well to manifest monetization of it.
