Most relationships are a waste of time. Some friends like to exaggerate, lie and show off. Others are negative and dull. These friends occupy your time and they affect your mental health.
Do not form relationships out of convenience. Do not fear rejecting friends or loved ones. Keep relationships light. Keep friends who share wisdom and can offer alternative views.
This does not mean you cannot be friendly and smile at co-workers. It just means being superficial and guarding your heart. Some older relationships are no longer useful. Let them go.
All relationships drain us. Cut off those who plays victim. They are a pain to be with. They keep us from feeling fulfilled. Keep sceptical people, they help to diversify your views.
You should simplify relationships at all costs and minimize burdensome relationships. Shallow relationships lasts longer because they are not draining.
