Self-acceptance: Self-deprecating remarks and thoughts will shroud your mind with negativity and foster increased levels of stress. Seek out and embrace the positive traits of yourself and your life, and avoid measuring your own worth by comparing yourself to those around you.
Optimism - Looking on the bright side increases your ability to experience happiness in your day-to-day life while helping you cope more effectively with stress. Always hope to see the positive in everything. This would help you push amidst dark and challenging times. Accomplishing goals, even small ones, can help you to build your level of hope.
