The problem with common sense is that you will find it is not that common.
It really is about how you play the game that is important. Play smart but fair. You may not always win but it is nice when you do. (See “huge gloat” lesson)
When your friend, partner, lover appears in a truly hideous, not-so-flattering outfit, gently tell them they look as though they have dressed with the lights off and suggest something else. If they refuse, accept that they have their own style and suck it up.
Find a perfume that QUIETLY announces your arrival. Avoid the ones that trumpet your existence from 50 metres.
You will only get out of life what you put in: treat yourself poorly and without respect: others will too. Treat others poorly and without respect and they will treat you even worse.
If you know your new lover is cheating on their spouse or partner to be with you, then chances are they will cheat on you with someone else. In the immortal words of Dr Phil: “If they do it with ya, they’ll do it to ya”. You can count on one hand the relationships that have started this way that succeed.
Sometimes the best travel experiences come out of cheap, inexpensive places. You do not have to travel in 4 or 5 star luxury to see the world. As long as where you sleep is safe and secure, it costs very little to look, smell, feel and taste different places.
Coffee that is poorly made never lives up to the anticipation.
Seeing as 90% of enjoyment is derived from the first three bites of something, do you really need to eat the whole packet of biscuits/ice cream container/(insert yummy thing of choice here).
If you want to try something, then give it a go. What’s the worst that can happen? (Except for speeding cars, taking drugs, accepting free drinks at nightclubs, eating rat sac or running with scissors).
Ask yourself “what is the worst that can happen?” If the answer is one you can live with, do it. Do it now. Life is too short to be held up by fear.
