At some point in our lives, we were taught to pursue our passions. We were taught to speak about our dreams and desires using the word "passion"; and that word, at least for me, has become overused in conversation, interviews, content I consume on the internet, and so on.
The dangerous part about passion is that it is hard to measure. Because we have so many things we seem to be passionate about, it is difficult to decide which passions are viable options to turn into a business for yourself. I freaking love tacos. I would say I'm extremely passionate about tacos. But would people pay to watch me eat tacos?! Well maybe... but those are not the kind of people I'd want to serve if you know what I mean! So many of our passions would not translate well into a profitable business, so you can absolutely start with passion, but you have to take it a few steps further.
Most people will not want to just pay you so that you can participate in your own activities of passion. You have to provide some sort of skill, service, or product to your customers, usually indirectly related to your passion. For example, people may not want to watch me just eat tacos, but they may want me to come into their homes to help them prepare a nice meal before their spouse comes home. That is connected to my passion of food and cooking, but it is now marketable. See what I did there? The key is to choose a passion that you can connect with a service or product that customers want to buy. It is the intersection between those two pieces that allows entrepreneurs to launch profitable businesses. And not all businesses are passion-based, so there are plenty of profitable businesses out there that began just on customer demand and not necessarily based on passion. That may not be the direction you want to go in, but it shows that the most important part is the process of translating an idea into something that people want to buy. You can follow your passions but if you're not making money, honey, you may want to rethink your methods!
