Don’t let what others think affect your thoughts, feeling or energy vibration.
Always when others feel the need to criticise or always look to the negative it is a mirroring of their own insecurities.
There are many who still live in self limiting belief and come from a place of lack. This is their experience and is for them to work through, what you need to do is step away so that how others are feeling does not affect you.
You cannot allow others to influence your decisions, just as you cannot influence others, it is not your job to do this, it is all about making your own life experiences.
What is happening is that they are vibrating at a lower energy frequency and if you allow them into your thought process you will lower your vibration too.
This immediately puts you out of alignment in your attraction process, causing you to exercise further to bring your energy vibration back up to the high vibration needed for manifestation.
Better to not give them thought and keep your vibrations high!
