Self-compassion entails being warm and understanding toward ourselves when we suffer, fail or feel inadequate, and NOT to judge and criticize ourselves harshly. For example, you would allow yourselves some relaxing times without feeling guilty even in a very tight schedule.
Belongingness is a subjective experience that you feel being accepted and connected in a relationship or part of the community. The social ties provide emotional support, which enhance your psychological well-being. For example, you may find belongingness in your family relationship, courtship, friendship, student society, volunteer team, church or university.
Optimism is an attitude or a belief that you opt to stay with adversity with hope and explore its positive side as well. For example, you choose to face the challenge of academic failure or ending of a romantic relationship with positive thinking.
