As the saying goes, where there's smoke, there's fire. But you can't recognise the fuel by the smoke alone. It could be a campfire with a lot of damp wood or a pneu factory that produces a lot of toxic fumes during a fire. From a distance, this can only partly be correctly interpreted from the colour of the smoke. The closer you get, the clearer it becomes - and most clearly when you are standing in front of the fire itself. It is the same with us humans: what drives us, i.e. what fire burns within us, can only rarely be correctly interpreted from a distance or by simply observing our words and actions. But if we get closer to people, we can judge much better what really drives their actions. For example, supposedly good deeds can come from bad motivation or with devious intent. Where there is smoke - take a closer look. But you should also keep checking yourself to see what fuel you are using to feed your own inner fire.
I wish you an extraordinary day!
