Goodbye to standby

Switching off devices that have a standby mode, such as televisions, computers and CD players, is very easy to do and can have a big effect on our power consumption.

However, to change their ingrained habits, people need to show strong determination.

They could post notices around the flat, reminding them to turn off their gadgets.

As well as individuals, the government and environmental organisations play an important role.

They could provide leadership and encouragement by launching campaigns based on, say, 20 ways to save the planet.

In the form of competitions, exhibitions and advertisements, the campaign could help raise public awareness and outline practical steps to help save the planet.

The pitfalls of tutorial classes

Tutorial centres claim they can help us achieve good grades in public examinations, and more and more students are taking their classes.

They seem to have a lot to offer.

However, these tutorial centres advertise a great deal and I think most of the advertisements exaggerate the tutors' abilities.

Some tutorial centres claim their students achieved more than 1,000 As in total this year.

However, a large-scale tutorial centre may teach many subjects and may be part of a larger organisation. Therefore, their claims may not really be that impressive.

There is also a lot of evidence showing we can get good results without tutorial classes.

If you really think you need help, there are some cheaper courses that are just as good as the expensive ones.

We should learn to judge what is real and what is fake so we won't find ourselves in a useless, inefficient and costly tutorial class.

Loving a colour-blind world

Once, when I was clearing the music folder on my computer, I found a song with an unfamiliar name.

The title of that R&B track is Love is Color Blind.

When I heard it I was touched by the lyrics, which are more than the words to a song - they are also a campaign slogan:

'It doesn't matter if you're black/ white or yellow, if you're brown and red/Let's get down to that/love is color blind .../Put away your prejudice/Open your mind'.

The worst thing in the world is discrimination - it destroys precious, innocent smiles. Global peace can only be achieved by spreading the anti-discrimination message.

Cultural and sporting idols are influential with young people and they should take the lead in enlightening the world.

Love should be colour blind; the well-being of the world is worth more than anything else. Let's fight for world peace!

Facing challenges

From the moment we're born, we face endless challenges which we must overcome.

From time to time, we may feel frustrated and it may seem impossible to deal with all our troubles.

We need to change our way of thinking, accept that we are human and be more optimistic.

Being lazy does not help either. Even though relaxation is essential, we ought to treasure every day and try our best at everything.

Save our environment

When I was young, I had to wear a lot of clothes during the cold winter. But that has changed.

In recent years, the temperatures in Hong Kong have risen because of the greenhouse effect, which is making the weather chaotic.

The city is not only very hot, it also suffers from serious air pollution.

Many foreign businessmen take the air quality into consideration when deciding where to locate their enterprises.

If we do not do anything to lessen the greenhouse effect, there will be four summers each year and our economy will also suffer.

We need to take action, and the government needs to make detailed plans for land use and create laws to protect the environment.

Go on, have a hug

Modern city life can drive us apart and make us overlook the nice things around us.

It is not easy to have a hug in Hong Kong because of the traditional thinking of Chinese people.

We rarely hug family members or friends, let alone strangers.

We feel embarrassed, even though love is essential for our mental health and hugging can show love.

Let's show our love for our family and friends by giving them a hug.

Success and luck

When we fail, we always grumble we're not lucky enough.

But failure is the mother of success.

When we face difficulty, we should try our best to overcome the problem.

We will only succeed if we give it our best.

Success or failure is controlled by ourselves, not by luck. If we try hard enough and persevere, we will succeed.
