Negative comments from others are their own insecurities…
In most cases, negative comments from others are their own fears or insecurity being projected onto you. If you allow them to, these doubts will seep in and throw you off your path. It is important to have positivity around you during this time. Only share your dream with people that you know will support your endeavors.
My friends & colleagues have given me this advice to help me with difficult people in my life. Takes a lot of practice to ignore comments though but the more you do the more empowered you feel. ~ Julie Rhodes
You let it define you or shape you. You lower yourself to it or you rise above it and be happy and successful. As long as your conscience is clean and your sleep peacefully at night, knowing you have been dignified, and the best representation of yourself for that day, you did well. ~ Donna Pascal
Keep my peace, mentally project love into that person who so obviously needs it, mentally tell myself, “This is not my truth”, provided I can’t just walk away. On days when I can’t hold my tongue, I’ll counter with a positive comment. Negative people tend to avoid you when you do that, and you still have done some good by releasing positivity into the Universe. ~ Etelka LaFontaine
All dreams can become your reality, surround yourself with positive upbeat people who have your well-being foremost in their mind, be there for others yourself with open arms and heart.
