I espeically like the last sentence of your post - reminds me of a famous Einstein quote:
Insanity: doing the same thing over and over again and expecting different results.
Even though there are rumours it's not his quote, it is still 100% true imo.
I am thinking about this quote a lot since I am no stranger to do the same mistakes over and over again.
Probably should get a tattoo of it :-)
