And that is the huge benefit of having a genuine passion for what you do. It keeps you motivated even as you pass through the dark tunnel of your career choice.
This week I had to pull out of a consulting job that got me steady monthly income for the last one year. I can't cope with the stress of working from morning to night everyday anymore, and I needed to let go of my most time demanding projects. On one hand it looked like a terrible decision -- I no longer have a monthly retainer gig. It's back to the beginning. But on another hand, I would rather spend more time doing the things I thoroughly enjoy rather than cutting down on them to give all my time to income generating projects.
I jealously guard my passion and ensure that I do only the things I have passion for. It makes every phase of my life enjoyable regardless of the low output my huge inputs generate.
