This is not a usual expression in English. One is more likely to say: Find happiness. Bliss means joy, pleasure. Follow means to go after. Hope this helped.
What Does Follow Your Bliss Mean?
Follow your bliss is a quote by the late Joseph Campbell, expert in mythology. Among educated English speakers (Americans) you'll hear this expression. What is meant by this phrase is to do those things that bring you joy - follow what brings you joy.
