Roses aren't always red & violets aren't exactly blue, the society we live in never seems to speak the truth. Smiles aren't always happy & frowns aren't always upset, people judge too quickly & our feelings are what they forget.
Be honest with yourself about what sparks you and take action on it. Don't worry about finding your one true "passion." That's too abstract of a concept to figure out logically. Instead, start by acting on the small things that excite you each day.
