I agree with you that we can't depend on anyone for anything, we can only rely on ourselves which means we have to be responsible for ourselves.
the sentence at the beginning of your post reminds me of one of the Bollywood movies "3 idiots" where ranchondas says to his friend raju, "you are not right to depend on anyone in life" he continues with the magic mantra sentence "al iz wel" that's the storyline Good.
Thank you very much for sharing this post and your work is truly extraordinary and a motivation for anyone who reads it ☺️
