In reality, there are only a couple of ways to get rich in consulting. Of course, it all depends on how you define “rich”. For the individual entrepreneur who runs a consulting business, from his income figure he must deduct all his expenses, which can be many. The rest can be taken as salary and dividends.
The best independent management consultants earn very high incomes. So it's 100% possible for you to do the same. However, if it were easy, everyone would do it. That's why taking intelligent action needs to emphasize “smart” work, not “hard” work.
If you brainstorm and discover some growth tricks, you could earn more money for the same work. That's why it's crucial to be active in the online consulting market and seek help from independent consultant platforms that can connect you with the right customers. However, your challenge, if you want to get rich, is to develop assets—in addition to your intangible knowledge—that can be exploited, expanded or sold by the millions.
