24. Be self-aware, not self-indulgent.
Being aware of yourself and your surroundings is so necessary. Know who you are and be confident in who that person is.
That said, there’s a fine line between being confident in who you are and being completely immersed within yourself. Because really, no matter how cool you believe you are, there’s someone out there much cooler; no matter what trials and tribulations are going on in your own life, somewhere in the world, someone is going through something 10x worse.
