Do you enjoy the media coverage about polls? Perhaps you should give back to the community.
Do you live in a swing state? Your preferred candidate may change their campaign strategy if they have reliable data on how they poll in your state (eg dial back campaigning where they are clearly ahead/behind in favor of where they are tied)
In the US I'd prefer not to say unless I've had some evidence I'd stay anonymous. Too infected debate.
After school I had one week of cash left when I got my first job. I moved to a tiny town to work in the mining industry. Pay to cost of living is very good. I've always been careful with money and dislike shopping.
I save about 50% annual income. This is piled up in various investments. I can retire before 40.
I have about 1 year worth of expenses in cash I can access tomorrow. I try to keep at least 3 months but I'm squirreling away extra for known upcoming expenses.
