"there are no pockets in shrouds!" That for me reminds not just about financial situations but that your care and help for other people is not limited and if you can do a good deed, do it!
The other one is "as far as we know ,no one has come back to tell us any different, we only have one life so live it the best way you can." Even when things have gone wrong I have always been glad of the many experiences I have had in my life, and dont remember how much I spent on a dress or whatever. It is the people I met and the things that I did give me pleasure to think about now.
