Watch your language and how you speak to others.
If you have a genuine desire to help someone and give advice try to pay attention to what you say. For example, try to steer clear of telling people what they "should" do, or deem their choice as right or wrong, bad or good. That is, you applying your moral code to someone else's actions and quite frankly it is up to someone else to decide what is right for them. Start noticing why you might have certain thoughts in that moment. Avoid using words that are overly negative, condescending or critical. For example, instead of telling someone what is wrong for tell them try suggesting what alternatives you use. Instead of telling your friend, "It's wrong for you to drink sugary drinks, they are disgusting." Try saying, "I try my best to avoid sugary drinks, and when I do I feel healthier." It's all in the delivery of your message. When you strive to be more compassionate and less judgmental your relationships will thrive.
When we feel judged by others we are hurt, so why do we continue to be judgmental towards others? It’s a vicious cycle that eventually destroys friendships. Harsh judgment of others destroys empathy. And empathy is what fuels trust and intimacy. It is impossible to have a healthy adult relationship without trust. How can we trust someone when they are constantly judging us?
