"Follow your passion" is a cliche now. Everone thinks it is is the fashionable thing to say. In reality, it is often a lazy thing to say. I agree that we should follow what our heart tells us, but a little thinking never hurts. Often, following your passion makes you realize you have wasted precious time and resource. What then? Some suggestions:

1. Focus on a Problem: Problem related to your passion. It helps you focus.
2. Find Your Positive Core: Who said it was going to be easy? Suck it up!
3. Don't Choose One Passion: With time, yu learn new things, get new data...and all this should change your reality of things.
