Well said, I would love to point out too that the Market rewards the Patient over the Impatient, the emotions of investors is what pays others that don't allow there's to control them even in the face of fear, this has been preached over and over again. For investors and newbies to look with a long term view, as well risk within there tolerance level which will keep them in a position of caring less and not panic because of price movement.
This is one of the cornerstones on the investment strategy of Warren Buffett, someone not overly appreciated here due to his comments regarding this market, but that knows way more about investing than we do, so listening to his overall strategy to learn a thing or two makes sense.
Can a trader in theory make more money than a long term holder? Yes, but how many traders can actually do it? Very few.
Holding requires a long term approach to the assets in which you invested and the ability to control your emotions to not take a bad decision on the heat of the moment, two abilities which can be hard to come by these days, but which can be developed as long as you are serious about becoming an investor.
