Self Encouragement is useful when no one else is around to encourage us.
It prevents depressive and suicidal thinking as we create positive brain activity which helps us to manage and eventually solve whatever problems and challenges we experience over the day.
A quite word to oneself
'I am a beautiful person'
(whichever words you find uplifting),
'I care about ...'
'I make mistakes but I can learn from them',
'I focus on goodness'.
