There are enough difficulties that abound in life. Some things are "easy" with a modicum of care, attention and perspicacity. Here are a few:
Getting to places early and not using "traffic" as a perennial excuse.
Being ready for things you ask other people to take time out for.
Expressing courtesy and acknowledging service providers.
Smiling when you make eye contact.
Helping someone if you can, with bags, a door, to find the way, or simple information.
Letting mothers with small children they are trying to manage and navigate with, know all is well, and they are welcome to do what they need to.
If you know someone had a personal issue, referring to it gently, or asking after them, or to letting them share if they want to.
Checking to make sure what you promised to deliver was actually received and experienced.
Sharing a real opinion when asked. Not feeling obligated to tell others "how things are" when not asked.
Catching people doing a good job and sharing that with others.
Is any of that "difficult?"
It's easy, so let's keep it that way.
