Dismiss them immediately and replace them with righteous and positive thoughts before they take root and become a stronghold.
Being positive is a choice. But for some they thrive on negativity. Counting others blessings not looking to there own. Negativity can be in families for generations. It only takes one to break the cycle into positivity and learn to live life to the fullest with goodness. ~ Wal Hall
Negativity is the cancer of the soul that spreads like a flu.
Do not try to destroy any thoughts that are arising because they will destroy you. Rather observe them as they come and go. This way you are not giving any power to them and when they get no attention they become weak and disappear. Realize that the thoughts are not who you are. Who you are is the one who is watching them. Positive and negative is the creation of the mind, they are just thoughts. ~ Karina Radova
Sometimes it is better to just walk away from those who always carry negative thoughts.
If you don’t they will destroy you, but you can turn negative things into positive action, just some food for thought!
