1 So I'm going to suggest

that less stuff and less

space are going to equal a

smaller footprint.

2 First of all, you have to

edit ruthlessly.

3 We've got to cut the

extraneous out of our

lives, and we've got to

learn to stem the inflow.

4 . . . we combine a

moving wall with

transformer furniture to

get a lot out of the space.

My bed just pops out of

the wall with two fingers.

5 Most of us, maybe all of

us, are here pretty happily

for a bunch of days with a

couple of bags.

1.1 Less stuff, more

happiness

1 by about three times

2 credit card debt and

their environmental

footprint

3 Happiness hasn't

increased.

4 it saves you some

money, you have a

smaller footprint and

smaller utility bills

5 Hill means that he only

has his 'favourite stuff'

and gets rid of the rest of

his unnecessary

possessions.

1 He mentions letting go

of a shirt he hadn't worn

in years and only keeping

items that 'we're going to

love for years'.

2 By this he means space

efficiency and designing

things for how they're

used the majority of the

time. In particular, he

mentions a six-burner

stove when you only use

three burners and he says

we want things that nest,

stack and digitize.

3 Examples for

multifunctional spaces

and housewares include a

sink combined with a

toilet, a dining table

which becomes a bed, a

foldaway office, and a

moving wall with fold-

down beds.

1 He mentions going from

3,000 to 2,000 square feet

so is suggesting reducing

our living space by 30%.

2 That they are happy for

a few days with just a

couple of bags and

staying in a small hotel

room.

3 Life editing will give us

more freedom and time.

4 The symbol < = >

means less equals more.

Overall, the answer is 3

because Hill attempts to

persuade his audience by

using objective facts.

(This main aim is in fact

true for most of the TED

Talks that students will

watch with this

coursebook.)
