Although winning the lottery would drastically change the course of your life and aid with either eliminating debt and paying off bills relatively easier, it would result in happiness but this does not guarantee that you will be, as you stated, "extremely happy for the rest of your life". The resulted quality of life may ultimately depend on how smart you are with your money. Although there are enormous positive outcomes of winning the lottery, lots of cons are present with it. One being most present is stress due to the possible constant staggering of family members or distant relatives asking for a loan or some extra cash to borrow. Not to mention solicitations from investment consultants, financial planners, and even con artists. Not every person is the same and not every person will experience intoxicating feelings after winning the lottery. However, acquiring a large amount of money would lead to the feeling that they are more "invincible" or more capable to do things just because of their financial wealth. People who are more grounded and know how to use their money wisely are more likely to live a happier life with their wealth than those who don't think rationally about it. to summarize, winning to lotto could result in either a stressful life or an extremely happy life, but the ultimate factor for this is typically decisions you make with your money and what you prioritize.
"Money doesn't buy happiness" my ass.
Probably. It would allow me to live the life I live now (which makes me extremely happy) without having to worry about where my money would come from (also tends to make you feel good). Of course, other things could bring me sorrow, but by and large it would increase my happiness.
It depends on if you can avoid becoming an idiot who blows it all within a year. If you can properly invest it or save it, then yes. If it is wasted, then you might actually feel worse.
It really depends on how much money you already have.
I believe we all have essential needs and all of them need to be met in order for somebody to be happy but having financial freedom would deffinitly fulfil many of those needs so I'm iffy
