The future belongs to those who can adapt to change quickly.
Following your bliss is a recipe for paralysis if you don’t know what you are passionate about. A better motto for most youth is “master something, anything”. Through mastery of one thing, you can drift towards extensions of that mastery that bring you more joy, and eventually discover where your bliss is.
Happiness is not about getting what you want all the time. It’s about loving what you have and being grateful for it.
