Unsolicited Advice #01
You do not live in a vacuum. Your actions affect the people around you. There's a thread woven between you and all those who you come into contact with. Never assume you can live your life as you please and it not in some way impact others. Whether you see the effects of your decisions or not, something is changing, someone is seeing or feeling things a bit differently. It's never just you.
Now whether your care what that impact is, or consider the consequences your problem, is a different matter entirely. I say aim to live a life cognizant of the potential aftermath of your decisions, words, and actions, good or bad.
