SAFETY FIRST
You never know when you’ve going to need one, so it is better to be safe than to be sorry you did not take the time to plan ahead.
To be better safe than sorry is to be cautious or prepared so that you do not later make a mistake. People who are better safe than sorry arrange and organize ahead of time so that they do not have to face negative consequences in the future. This may mean they are physically safe or that they are safe from bad events.
