If you had to start a new business, these are pointers- I myself am into consulting, in case you are curious.
Do something that will let people
-gossip through ridiculous forwards - WhatsApp
-show off- Instagram, Facebook, etc.
-not do what they should be.. cleaning, cooking, going out.. all delivery businesses, in short.
-be couch potatoes- Netflix, Amazon Prime and the rest..
-not sure if physical dating is still required to get into relationships/marriage etc., so will add online dating and matrimony sites too.
What else? That covers most of it, I think.. anything that promotes laziness, in short.
