When you go for a coffee or meal with a friend, if you can afford to, pick up the whole bill yourself.
Return the Wallet
If you find someone's keys, phone, purse, wallet, handbag etc. return it to them, complete.
Give One Free
If you buy something you wasn't expecting to be in a "buy one, get one free deal", give the free one away.
Run/Jog/Walk 5k
Whatever pace you are comfortable with, do a sponsored 5k to raise money for a good cause close to your heart.
Turn IT Off
Turn your computer, and other electronic gadgets where possible, off overnight to save electricity, money and the planet.
Forgive A Debt
If someone forgets to, or cannot, return/repay something they borrowed and, if you can afford to, forgive the debt and never bring it up again.
Put It Back
Take the extra moment to actually put something back on the shelf you got it from if you decide you no longer want to buy it. Get out of the habit of just leaving your unwanted items on a random shelf for someone else to deal with.
Wish Them Luck
Buy lottery tickets and hand them out to strangers.
Stop and Listen
When you see a busker don't dash past, pause a while to listen and, if you appreciate the music, throw some decent coins in their hat.
Share the Savings
Let your friends know about great sales/voucher codes you have spotted – everyone loves a bargain!
