How Come You Don't Need To Watch The Market???

One ex-colleague knew that Uncle8888 was busy running here and there and asked him : How come you don't need to watch the market?

Hmm .. First thing first!

Uncle8888 is not a day trader trading for a living. 

With his investing strategy of (1) No stop-loss and (2) Make hay while Sun shines and not pulling out winter weeds; so there is no serious need for him to watch the market closely. 

He sows his seeds!

His harvest will take days, weeks, months, years or never. 

So why need to watch the market so closely? 

For what?
