The quotes I like might not be Grandiose but they arrived into my life at the right moment and helped me change perspective.
Chrono Crusade gave a few that I ended up writing on my pad holder so I could be reminded of them. The wording might be different but here they are:
Quote:I can't predict the future... but just because I can't I don't want to leave it to the side for when it's too late. I want to do what I can right now and I want to give up only till I reach the conclusion.
Quote:After acknowledging your fear, the important thing is to overcome it.
This one is the revelation that having courage doesn't mean to be fearless, but acting even through your fear. It was a big deal for me, because I grew up guilt tripping me about my fears and made me realise that fear is not pointless or a de-facto sign of weakness.
