(Please do not refer to any previous posts I have made while reading this, I do have multiple personalities and this one is saying this today. Besides, all of them together make sense.)
The title sounds somewhat silly and obvious, like, who else can someone be but themselves. Ha-ha. I know that of course. What I'm talking about is in a deeper sense. Its not very difficult either. My mentor has always been teaching me lessons leading up to this ultimate acceptance of others actually. She used to tell me to not take things too personally and not be too emotional. Being me, this was very hard to do as I'm a very emotional, liberal, outspoken, heart-on-sleeve person.
However, as I have matured I get it. Simply put, it means exactly what it says. Accept a douche-bag as s/he is. Accept people who stab you in the back as they are. Accept selfish friends as they are. Accept insecure people with their insecurities. Try by all means to not try change an adult from what works for them. All you have control over is yourself, your thoughts and your actions. You can also control the amount of self-exposure to people.
This lesson has been a tremendous help in my life. Combined with the not taking things personally, aaahhh, bliss. You know when someone comes and bitches and you're like, ookaayy? Yeah, I'm that person now. I do not take people's attitudes or emotions and make them change how I am feeling. Its theirs, I let them own it. Why stick around a pothead if you're just gonna bad-mouth someone who probably graced you with awesome company and very 'conscious' conversation? Rather stay away. Accept people you choose to spend your valuable time as they are friend.
When you accept people as themselves, you start believing them when they show you who they are, without complaints nogal. If you don't like the person as they are, why stay in their company?...ok...work neh? Well, you could choose to be prefessional and not make small talk with such a person. There's nothing wrong with that. You're mos not there to make friends. Actually, not accepting someone with their crap and still being in their space is a form of abuse. Are they now expected to conform with your likes cos you're there? Do you speak Chinese when you go to a Chinese restaurant? Aha, you see?
