Of all the emotions I have ever experienced in my life, the most constructive & motivating one somehow has been the emotions evoked by Jealousy.
I feel jealous when I see people having a great social life – I build a social life for myself.
I feel jealous seeing famous people – I do something appreciable & noticeable.
I feel jealous looking at my friends buying cars & houses & going on international vacations – I work hard to save enough to be able to do so myself.
I feel jealous when I see a friend have a hot bikini body – I hit the gym & workout hard!
