Looking to start my retirement fund. How many things shoud i put money i to

So ivd been putting away 1000 a month into into savings 250 into a roth and 250 i to stocks (big texh companies, memory manufacturers that kind of stuff) but im wondering if i should invest into anyrhing differnt or change around my budget. Any advice. I dont want to make money right kow so nothing volatile just a slow burn thats very unlikely to go down in the next 50 years
