Recently Adam Grant had a great podcast on the dangers of following your passion at work. What do you do if you don't know what your passion is? Even if you do, following your passion can lead to tunnel vision, causing you to miss out on other opportunities.
Even worse, following your passions removes you from the growth mindset. We are rarely passionate about areas we don't excel at, and it takes practice to improve.
His suggestion? Follow your curiosity. What areas do you get excited about learning about? What areas make you want to grow? It's that quest for knowledge that will keep you going and ultimately help you develop a passion for what you do. Yes, you should even have a growth mindset about your passions.
So focus on developing, not following passions.
