Sometimes life could be likened to the scenario within a traffic control post.
Some vehicles arrive when there is a yellow indicator.
Some meet the red indicator,
while some sight the red indicator from afar and as they approach the traffic post, the green indicator has already shown.
In a situation where there are fewer vehicles, the last batch usually overtake those that arrived early.
Also, in some cases those who arrived the control post early loose focus and feel very relaxed just for them to realize that those behind are already overtaking them while others are blowing horns for them to give way...Such is life and it's quite amazing.
