you do not have to make basic errors/experience everything yourself - many blogs & fora are full of crap as well as good advice - from people who think their stupid errors are to be expected!
Research PROPERLY online & through libraries/books - using established & recognised sources - eg for growing your own veg, start with The Soil Association, through Hessayon, to Bob Flowerdew - this could save you a LIFETIME OF DISAPPOINTMENTS...
