When I say scales, you probably think about a healthy physical weight or balance.
Especially balance is important, not just physically but also mentally. When you think about your life: how much weight do you put on the positive experiences and how much on the negative experiences? Wild guess, but there won’t be any balance because the negativity tips the scales.
In fact…most people give more “weight” to the negative experiences. Now (unfortunately), some people go through very negative experience in life which have a great impact on their life. And in that case it’s logical to give more weight to the negative experiences. On the other hand roughly said, you have the “average” person who’s had a normal childhood, with a roof over his head, educated, a (loving family), with the conveniences of the modern Western world and freedom. The funny thing is that the people who’ve had very bad experiences or have less are more likely to give more weight to the positive things in their life.
