It’s nice to get a bit more, isn’t it? At a restaurant when you get an extra serving or find some money on the ground. It can be very tempting, sometimes irresistibly so, to take more than your fair share. The last piece of cake. The food you’ve eaten but isn’t on the bill. On the other hand, it’s really annoying to get short-changed. Missing out on the last biscuit. Having to do the unpleasant job again because there’s no-one willing to do it.
The thing is, both of these are two sides of the same coin. Sometimes there’s no loser and it just good fortune but that’s pretty rare. If you find money, someone has lost it. You take the last biscuit, someone else isn’t getting it.
Where am I going with all this? Put in more than you take out. Why? Because. If you put in extra someone gets more than they were expecting. Maybe it’s a slice of cake, maybe it’s help with the cleaning. You might be doing more now but it’ll come back your way on another occasion. Do the extra job, go the extra mile. What’s the alternative? Everyone does the opposite and takes more away than they put in. There’s a lot of that already, let’s not do that, it doesn’t end well.
