- have 6-12 months of emergency cash that can sustain you if your main source of income fails. something will always happen, whether it's an appliance or car that breaks down, or an unexpected medical expense. slush funds are good.
- 'if it ain't broke, don't fix it'. make stuff last the extra mile, if you can. stretching electronics and clothes .... fixing electronics (when realistic) instead of buying the new shiny thing ...
- don't sell stocks. if anything; if you're fortunate enough to truly have extra cash, buy that stock at rock-bottom prices you've been eyeballing for a while. buy low, sell high.
- if you have dependents, be extra conservative with your cash. you will need each other.
- this too, shall pass.
