Be authentic. All the time. We are all still trying to figure out where we want to be, how we want to be, and with whom we want to be around when we are being or doing these things. As we are growing and exploring, always being honest with yourself and others along the way. It will enable or foster the ability to gain respect from others. People will not always appreciate our actions or choices, but having their respect comes from them knowing that this is a sincere attempt on our part.
We have a finite amount of time in this life. While we have it, do the things your future self or those in the future would look back on, with admiration. Always try to be on the side on a decision you feel as if you will be able to live with 20 years from now, as opposed to hoping that you can make up for it in 20 years from now. Be authentic. All the time. Be what you want to be and do the things you want to do.
