Impatient drivers in traffic jams often pay lots of attention to what lane they are in and how the other traffic lanes are doing compared to theirs. If the other lane looks like it is moving faster, they often will swerve over to cut in front of somebody else. Some people do this repeatedly, taking every opening they can find to get any slight advantage for themselves. Those drivers may indeed gain a few seconds. But in the process, they escalate the levels of danger and annoyance to them and everybody around them.
Impatient investors watch the market from day to day like a hawk.
But except for market timing purposes, their time would be much better spent studying what's happening in society and the world, looking for investment opportunities over the next five to 10 years. Impatient investors are easy prey. They can be lured to change lanes, and change lanes again. And they end up as road kill, often retreating to the sidelines with money market funds and Treasury bills while their more patient counterparts build their wealth in the slower lanes. Patient investors who make investments and stick with them for years or decades, with or without market timing, aren't likely to have exciting anecdotes to share at parties.
