The greatest wisdom my mentor shared, "making money is hard"

Honestly speaking, there is this strange belief among some entrepreneurs that they will have an idea and it will be successful, and they'll be rich. No, making money is hard. There is always a lot of work that needs to be done, it is time-consuming, it requires persistence, you will need to constantly think and make changes to your workflow, your product and how you communicate about it. It is something that every entrepreneur should be aware of, and go in with that mindset.
