The night before your birthday, you may be surprised to find a box of snack boxes on your doorstep.

It’s not your normal birthday gift.

It might be a surprise, a birthday present, or something else entirely.

It may not be a gift at all.

It might be the only thing in your life that you have ever received in a box.

But the box may be the secret to the joy of life.

“A box is like a gift,” says Dr Sarah Gilden, a social psychologist and director of the Centre for Health and Wellbeing at the University of New South Wales.

“It’s an opportunity for us to think about how we can do our best to give ourselves the best chance of achieving our dreams and living in a way that is comfortable, meaningful and fun.”

It’s not easy to find out what a box is, and what it contains, but it is easy to imagine what you would want from it.

A box of snacks?

A box of chocolate chips?

A package of snacks for yourself?

All of these things are good, but what about a box that was only for you?

“It is a box, but I have never seen it in my life that is for me,” says the box’s recipient, the late Sarah Gaulden.

“I think it is a really special experience for me because I am not a person that is looking for anything special.”

You can also think of a box as a reminder of your personal milestones.

You know what it is, right?

It’s a box for me.

You don’t know what to do with it.

You know what’s in it.

It can be a box or it can be anything.

“There are two kinds of boxes,” says Gildens.

“There are those that are a reminder that there is something in there and that you need to look at it, and there are boxes that are not a reminder, they are a celebration.

They are a really positive experience.”

The box is also a reminder for you to be mindful.

“We all need to take a step back and look at ourselves and what we have,” she says.

“If we do not, then there will be an enormous negative impact on our lives.

It will not be positive, it will be destructive.”

Sarah Gauldan’s box was given to her by her late husband John, a former nurse who died when she was 35.

She is survived by her daughter, her husband, son and grandson.

“I have this box that has never been used,” she said.

“But it is an incredibly beautiful thing.

It is my box.”
