The phrase, even the little things in life matter is sometimes a statement that is very hard to prove and something that is very hard to put into practice. This is because often the little things in life do not have a lot of meaning at all and they are simply there to make things better, or at least so it may seem. However there have been many examples of this in life and nature that we can see, where because the little thing in life was removed or added, there was a whole cascading disastrous effect to everything around it.
For example, many countries from around the world have sometimes sought to bring a small insect or animal in order to fix one problem. However this small insect or animal has sometimes turned around and created an even bigger problem as it would go and completely ruin the whole eco-system of the area. This is why, not taking into account the effects of a small difference can have huge impacts all over. Another example from the world of technology would be when an airplane maintenance person put on a small bolt on a windscreen of a plane that was half a centimeter too large. This difference was something so small, that it was never noticed until the bolt failed under the pressures of flight and came lose. In this horrific event the pilot was blown out of the plane and was nearly killed had it not been for his team who fought hard to save his life. This was all from placing one bolt failing to do its job because it was half a millimeter too large.
This is why the little tools and little gadgets have such importance. They can play important roles and have very critical functionality. Such as with a pogo pin socket which has immense value in the world of electronic testing or supercomputers but which is something that is often not known at all. Other such devices can include the fuses that we all know to ask for from the electricians, but it is something that most do not know what purpose it has or why it is important. Small devices and equipment like this may sometimes be famous, and some other times not so well known but for the people that use them and know about them, they play a very important role.
This is why it is important to make sure that you always have the right piece for the job and in the right way so that these little devices can do their jobs properly and even keep everyone safe and sound.
