Your mind will only think about achieving what you believe is in your realm of accomplishment.
If you think about how to get to making money, your brain will think of every side hustle or gigs you can do to bring in a few hundred to a few thousand a month
If you think about 100k a year, you may only think about doing a job or consulting for
8k a month.
If you think about 1m a year you may think about building scalable companies to 80k a month
If you think about 10m+ a year you'll think about how to scale even higher and how to get into company exits.
If you think 100m+ a year you'll think how to build an original product that can impact several lives, how to gain investors, and exit/IPO
If you think 1B+ you'll think about how you can create an invention that changes the world
Each time, your mind will be engaged in solving an equation that leads to the outcome you imagine.
Therefore what you choose to work on is more important than how well you work on it.
