I am daily proud of myself but i dont express to people, most of them struggle with routine, for me its enought i know about myself who i am.
You are the most important, you dont need to search approve or validation in anyone else or from people around you. This can be huge mistake and a road to self destruction.
Beeing proud of yourself sometimes its confused with arogance and many others bad qualities.
Diplomacy, humility will make you greater than beeing proud.
The only one who can be proud are the people around you, proud because they know you and to come from their decision not to implement :)
