This may be true in some cases, especially amongst newcomers, but it is certainly not true in all cases. I have day-traded for some decades and have no intention to change. It is not a case of “fear” at all. It is purely a question of finding what suits your character best.
I do not sit at a screen all day. I check in hourly on the hour and often not even then when it is clear that a signal to act is far away. The reason I day trade is because I like to see an immediate response to my entry and a good result with minimal time exposure to unexpected events. Most of the time I am not in any market and I do not need to carry positions in my head. It is incredibly relaxing to be able to decide when I want to trade and when I have other things to do.
It is also very relaxing not to have to worry about missing out on trends and whether the market is suddenly going to reverse on me. It does not matter to me what the market does overnight, every day is a clean sheet and you just patiently wait to see if anything happens. If and when it does then you enter with a target and stop and wait… Simple, methodical and entirely relaxing 
Yes, I will certainly state that with a straight face. I trade strictly according to a TA set-up. I look at the daily chart for the overall state of the market, then the 4-hour to determine where we currently are in that daily scenario, and then drop to the 1-hour chart to identify my entries according to what I am anticipating. If it doesn’t happen I don’t trade. If it does, then I am in. Sometimes, after entry, I will even drop to a 15 min chart to monitor how it gets going. I have a win rate that is consistently 70-80%, has been for ages. But the consistency in actual profit does not come from a high win rate, it comes from a rigid risk/money management.
For example, several studies on trading have been carried out using just a coin flip for entries, and these have shown that such a method can still be profitable provided the risk/reward is strictly managed. I have never tried such an approach but I can believe that it is possible. The main purpose of my TA set-up is to improve the probability level beyond 50/50. That is as much possible on intraday movements as it is on daily/weekly movements.
I do not find anything “exciting” or emotional about day-trading. On the contrary, for me it is a very concrete, mechanical, formalised process, with little room for flair or intuition unless one is just gambling on the markets.
There is no place for traditional fundamentals in day-trading except for an overall backcloth assessment of market conditions. I do not include news trading as “fundamentals”. I use the daily calendar only to watch what is on the horizon because certain events will impact market movements beforehand and that needs to be taken into account in day trading.
There are day traders and there are long-term traders. One is not superior over the other. They are different approaches based on different principles by people with different personalities. They both have their pros and their cons. But they both need similar qualities of experience, patience and discipline.
Everyone knows there are many gamblers and cowboy traders and I would agree that most of these probably trade intraday in (too) large position sizes and off-the-cuff rather than with a strict ruled-based methodology. I am excluding this category in my comments and am only referring to day traders who trade with a professional approach to their business.
