If you’ve got somewhere to go, or something to do, there are probably a few things you need to bring with you, or prepare in advance.
It may be some snacks for your travels.
It may be some materials for your presentation.
Whatever the case, waiting to organize these things until the final few minutes before departure is rarely a good strategy for success.
Control the controllables.
Set yourself up for success in advance.
Every thing you do now is one less thing to forget later.
