What is the best advice to give about life itself?
Life is impartial. The rich and the poor, all the the Race Colors, all sexual orientations - everybody experiences disappointment, joy, defeat, elation, health, despair and euphoria to some extent or other. Your life is YOURS. It is a journey which you share with others while captaining your own boat. The mistake is to forget you ARE the captain of your own life and then be living for the pleasure and purposes of others while denying some vital aspect of yourself.
We grow up being conditioned by others, (family, culture) yet we can later challenge and even drop that conditioning. Or not. Our choices shape our beliefs - which is what we then draw to ourselves (subconsciously) for future life experiences. Believe you are worthless and you will only draw that which reinforces the belief. Believe you are a force of nature with a worthy cause - and draw a different life experience. In either case the life experience comes from your beliefs..
Here's the thing, creativity and originality come from the conscious mind - beliefs are in the sub-conscious. You have to listen very hard, and be extra vigilant in order to become aware of your internal (automatic) programming, then you have to be very ‘present' to challenge what comes up - if you wish to change it. This is why old "habits" die hard and new ones take weeks to establish.
