Necessity is something that must exist in life. If it is not there, of course it will disturb your life and make you uncomfortable. I think investing is just a choice to make for the future, if you are okay after doing it. Investing is not a necessity where you have to sacrifice your health to do it. Many recommend investing only with cold money, so that it doesn't disrupt your life when something bad happens to your investment. Investments don't always make money, but sometimes they also cause headaches and generate losses. Especially when we make wrong decisions from wrong analysis or when the market doesn't want to compromise with us, it will really kill you if you use your hot money. Therefore I prioritize my health over investments.
