"Do what you love" is not about a job, a passion, or the money, and it is not classist. Our industrial society may have trained us to think that way, but we can change that. DWYL is the right of every human being born on this planet.
Most of us are gambling on the biggest risk of all: the bet that we can buy the freedom to do what we want later in life. In order to change the world and the less-than-promising course of history, we must do what we love now.
Hold tightly to your passion and never let go. Let it infuse your life with meaning and purpose and become the motivator for everything you do. Then, put in the hard work needed to turn your dreams into reality.
With each choice we make, our life picks up a little bit of steam, until, sometimes, before we know it, we find the life we're living is one that's being driven by inertia, heading off in some direction we never planned.
