This is true, but impractical.
When you are starting out almost no one knows what their passions are, and you become paralyzed because you can't give your all until you find your passion.
A better strategy is to forget your bliss and to find your passion by mastering something, almost anything. As you master some skill, giving your 100% to it, you will inevitably move toward your passion, step by step, all the while earning a living.
Most likely it will take all your life to find your bliss. So don't wait for your passion. Just master something.
