Accompany byusually refers to people, as in "he will be accompanied by his wife on the piano" or "...to the meeting". Accompanied with sounds wrong in this context.
'Accompanied by' is used when one thing is in the company of another thing. Perhaps my fiancée example should be 'accompanied by' only, rather than what I said earlier - that it could be both. In general, use 'accompanied by' with people.
She was accompanied by a friend.
The less common accompanied with, on the other hand, is synonymous with "in conjunction with" and would be used of things, as in "he suffers from a massive inferiority complex accompanied with a burning desire to succeed". (But accompanied by wouldn't sound wrong here, either).
'Accompanied with' is used when one thing is in some way linked to another. Perhaps the others are correct that this is a local thing, but I've certainly seen it used. Menus in restaurants often describe the food as 'sirloin steak accompanied with tartar sauce' or whatever. Also, when reading medical notes I often come across symptoms using 'accompanied with' - 'a sore head accompanied with back pain'. So, I think use 'accompanied with' with things such as these.
The highest purpose of your life is to be yourself to the best of your ability and live each moment as fully as possible.
not this moment
I do my thing and you do your thing. I am not in this world to live up to your expectations, And you are not in this world to live up to mine. You are you, and I am I, and if by chance we find each other, it's beautiful. If not, it can't be helped.
Gestalt prayer by Fritz Perls
I am Me. In all the world, there is no one else exactly like me. Everything that comes out of me is authentically mine, because I alone chose it -- I own everything about me: my body, my feelings, my mouth, my voice, all my actions, whether they be to others or myself. I own my fantasies, my dreams, my hopes, my fears. I own my triumphs and successes, all my failures and mistakes. Because I own all of me, I can become intimately acquainted with me. By so doing, I can love me and be friendly with all my parts. I know there are aspects about myself that puzzle me, and other aspects that I do not know -- but as long as I am friendly and loving to myself, I can courageously and hopefully look for solutions to the puzzles and ways to find out more about me. However I look and sound, whatever I say and do, and whatever I think and feel at a given moment in time is authentically me. If later some parts of how I looked, sounded, thought, and felt turn out to be unfitting, I can discard that which is unfitting, keep the rest, and invent something new for that which I discarded. I can see, hear, feel, think, say, and do. I have the tools to survive, to be close to others, to be productive, and to make sense and order out of the world of people and things outside of me. I own me, and therefore, I can engineer me. I am me, and I am Okay.
