Even if the ban is implemented, I doubt it will have much effect. Teens will simply find other places to take drugs, such as in parks or public toilets.

Will the government then move to ban teens from parks and public toilets too? Banning young people from internet cafes hardly seems like a workable solution to curb drug abuse among teens.

We must stay true to ourselves

Be yourself by being yourself. That may sound like a abstract concept, yet it is a significant idea that most people seem to forget.

As time goes by, not only does our physical appearance change but also our thinking. We may gradually lose the essence of who we truly are by embracing the values of others.

The older we get, the more we realise how cruel and callous the world is. Eventually, our values and beliefs may become distorted to help us cope better.

It's sad but true that we all crave the acceptance of other people. Yet such acceptance often depends on how well we can conform to their values. By seeking approval, we forfeit our own true values.

We need to stop caring about what other people think of us. We must have faith in ourselves and remember that there are people who love us just the way we are.

Life is full of temptations that may lead us astray - the temptation to lie, to do drugs, to profit in dishonest ways. One temptation many people fall victim to is the temptation to change their true selves to gain approval.

That's unwise. The key to real happiness and personal fulfilment is to stay true to ourselves and be proud of who we really are.

New SBA system will lead to failure

Under the schedule planned by the HKSAR Educational Bureau, students will have to do a series of school-based assessments (SBA) rather than just one.

SBAs are done regularly in some subjects. Each of them consumes lots of time and effort, which the government has simply not taken into account.

Every student must try their hardest to submit a perfect assessment as scores on each can affect our overall results.

The better your result, the higher your chance of getting into a university. As a result, most students pay close attention to SBAs.

I don't agree that taking a series of SBAs is a good idea. They might seem improve our education, but too much studying robs us of enough sleep.

By focusing on SBAs, we lose out in the end by being less able to concentrate on our lessons.

For this reason I believe that the newly formulated policy will led to failure.

We must scale back our consumption

Hongkongers consume way more resources on average than people on the mainland or even in many places in the developed world.

Our carbon footprint is very large. A recent report found that if everyone in the world enjoyed the same lifestyle as we do in Hong Kong, we would need 2.2 Earths.

That means we will have to scale back our consumption.

First of all, we must use less energy and do so more efficiently.

We should also implement many more environmentally friendly policies to preserve natural resources. We simply cannot go on squandering natural resources like there is no tomorrow.

For instance, we could create more reservoirs for the storage of rain water. We should also make good use of renewable energy sources.

In addition, the government should stop the resale of farmland for building projects. That way, we could grow more of our food in eco-friendly ways and avoid being over-reliant on imported products grown in harmful ways.
