Investments For Dummies

I just read in stock investment for dummies that stock investment is not good for short term.?
Short Term– Less than and year
Intermediate Term– 2 to 5 years.
Is that true that i can’t just learn the market and start making money. that I would have to invest for 5 years if i want to see safe returns.
If not what is the Best Way To Make Money fast, I mean within reasonable time (don’t post messages about stupid programs, trying to make me your refferal,, i will report you)
If you want a safe short-term investment you can invest in a money markets, CD’s, savings accounts, or Treasury Bills. None of these are going to pay much higher than 5.5% at current interest rates. Safe short term Investments are not going to be high paying. That’s just how the investment world works. If some one tells you they have a safe high-paying investment, they are probably a scam artist
