I heard that as a quote today and instantly fell in love, I think it’s pretty self-explanatory what it means and it’s a very valid question. To truly be happy, you need to do something that inspires you. This can be a very broad statement, maybe being an integral part of a company which values its people is perfect for you. Maybe you just love creating something very specific and you’re super good at it. Life is too short to start down a rabbit hole where you are doing something you hate to make a “living,” and as the quote eludes in this case you’re not making a living at all that way.
Find a way to make a living that keeps you inspired. It’s best for you, best for people around you, and will make you the most productive in the process.
