Thinking too much won't solve any problems. And if you let thinking over take you, you are only escaping in your own reasons for not doing anything.
In the current COI on the train faults last year, one of the SMRT train driver thought if he went out of his driver cabin, the passengers will panic and rush into his cabin. This driver decided to play safe and stay in his cabin.
On the other train, this other driver went out of his driver cabin and assured every passenger that all will be well.
The difference was that in the train, where the driver thought it was best not do anything, there was a smashed window as one of the passenger was reacting to panic from a close one who complained about breathing problems.
Being safe in your head doesn't mean it is safe in reality.
