I am a very stingy person.
I wear my father’s old shirts. I wear shoes with holes. I don’t have a car. I walk in the rain to save the bus fare. I never buy anything new if the old stuff still works. I don’t make presents. In winter, I put my food outside, so that I can switch off the fridge. I always look for the cheapest shop. I go to cinemas in the afternoon when films are cheaper. When I feel hungry, I collect mushrooms in the forest.
Some people seem to be put off by this behavior of mine, particularly women.
Thus, I was excited to see that Congressman Gary Peters, an equally stingy guy, it seems, made a virtue out of it:
He won the election.
Henceforth, I shall no longer be ashamed of being stingy, but I shall advertise it as a virtue and recommend it to others. Being stingy is cool.

Why give the money back to the state, they use it for global warming and such crap.
Give the money to me for my Krautfunding! Thanks.
But doesn’t Kraut cause global warming as well?
Not MY Kraut. My Kraut is cool too much!
I wouldn’t call any of that behavior you described “stingy.” Stinginess means not willing to share with others. At least that’s what in means in American English, I don’t know about in Britain.
I don’t even have anything to share with others.
Errr, in moderation, it is.
But as a previously stingy and sick person, to myself most often, I really don’t like being stingy anymore. The value of my life increased exceedingly when I resolved to start spending money on me.
But then you need to work to earn (more). I really enjoy working as little as possible.
Then save, invest, there are a lot of things you can do to prevent yourself from working after a while
Saving is highly overrated: https://andreasmoser.wordpress.com/?s=investment+advice
Frugal means “economical in use or expenditure; prudent saving or sparing; not wasteful”.
Stingy means “reluctant to give or spend; not generous; penurious”.
So which one is you or are you both?
You say you have nothing to share but you can always share your smile your compassion your kindness etc..
I am both. Maybe I read too many Scrooge McDuck comic books as a child.
