5、Smile and smile back
Are you a smiler? Chances are you could make a bit more effort. And help influence others too. We all know the Mr Misery in the office or Ms Glum at the petrol station. Get them to smile more. It takes up half as many muscles as it does to frown and it makes you and others feel twice as good.
Smiling also makes you appear approachable and more attractive. It says: ‘I like you, you make me happy, I am pleased to see you.’
People can even tell when you are smiling from the intonation of your voice. So smile when you’re on the phone. Start the day with a smile. Stick a reminder on your bathroom mirror.
You actually can’t smile too much, although American synchronised swimmers accepting Gold medals come pretty close.
6、Take public transport when you can
Is this a joke? Public transport sucks. I’m a free man and I have a car. I love my car and I’m going to use it.
This action tends to bring out extreme reactions. We love cars too, especially those new Smart convertibles. It’s just a question of balance. How many car journeys are really necessary?
When was the last time you sat on a bus? It really can be quite fun, especially on the top deck with kids.
Consider this: A double-decker bus carries the same number of people as 40 cars. And it’s going there anyway. Buses are seven times safer than cars and obviously more environmentally friendly. Imagine if everyone with a car took just one bus journey a week how much our carbon emissions would be reduced. And if you are driving to work or school, share the journey with a friend.

So, don’t feel too guilty about driving your new two ton diesel guzzler, just give it a rest occasionally
