the secret is to trick your brain to thinking that you are doing nothing wrong. and really? you aren't doing anything wrong. you're living--- that's what you're supposed to do. you can pay for your crimes later---but right now, you're supposed to live. make mistakes, get messy, break hearts, experiment, etc.
otherwise you're gonna live the rest of your life regretting it.
Do not sidestep your morals. They are there for a reason. Listen to them and do what's right. You'll feel better for it in the end.
Don't contribute to the breakdown of a civil society by falling into the throes of "live how you want no matter what anybody thinks - even yourself." It's contagious, if you can't tell, and it's destroying us, as individuals, as communities, as whole societies..and as a country. Listen to what's inside of you. do what's right..and then STAND UP for it.
