(-n) x (-n) = (+n)
(+n) x (+n) = (+n)
(+n) x (-n) = (-n)
Imagine the three equation goes in a cycle. It’s your cycle of life. Then that cycle of life, you’re going to end your day with +ve ending or either -ve ending. That number you multiply is what you’ve done in a day with the number you got from yesterday. If yesterday you got +ve number and today you did great. Then you become +ve at the end of the day. So, you’ll wake up smilingly positive again tomorrow and if you didn’t do great on the day. You’ll have a (+n) x (-n) so you will have a -ve ending on the day. You’ll wake up negatively tomorrow and if you made -ve thing again on that day. You’ll start to motivate yourself and then wake up inspired again tomorrow.
