When can you evaluate your life if it's successful or not?

Usually everyone of us has a moment when he feels depressed and his life is useless, so where is such a feeling coming from? Usually it's a result of comparison of your life at this moment and someone else, sometimes this comparison is happening in your subconscious, then later you get this feeling as a result. Also sometimes it is a result of watching movies or media where they have specific endings which drive you to that feeling. So when can you say for sure that you have a successful life or not. ============================================ motivational-epic-music-inspiring-cinematic-background-music-124265 Music by SoulProdMusic from Pixabay ============================================ #motivation #phsycology #lifeexperience #life #success #motivational #motivationalvideo #lifeprocesses
