one can spend end less amounts of time on "investing"
i like macro-economics and treat it as a hobby.
others that may have little interest in the subject could take a simple route.
25% gold/silver
25% blue chip dividend or index fund
25% property or rental
25% in your business or hobby, if you spend/invest in what you know and like will usually do well
same with work do what you have passion and ability=success
if #3 and 4 dont apply just put 20% gold/silver and 80% in 10 different good dividend paying blue chip.
why gold and silver?? because inflation protection against fiat currency. another note now not the time to by stocks, now is time to sell. buy after next correction.
