I'd thought I'll share some of my favourite quotes with you. Someone once told me that these can also be called 'affirmations' (positive statements), if you find them as words or phrases that help inspire and motivate you, as it does for me at times.
I learnt most of these during my uni days when I studied philosophy as an elective. I hope that they serve you as well as they have served me. If you're looking for some context, I do mention these in my posts from time to time (which you'll find tagged as 'quotes').

"a person is nothing else but what he makes of himself" - Jean Paul Satre
"Man's main task in life is to give birth to himself, to become what he potentially is" - Erich Fromm
"Reach what you cannot!" - Niko Kazantzakis
