You make a big effort to get to a client presentation, only for it to miserably fail. On the way out of the building you bump into an old friend who happens to run an investment firm which then buys a stake in your business. 

You fly to Nairobi to do a deal, only to miserably fail. Before flying home you catchup with old friend for coffee and turns out she has an even better opportunity for you. 

You do stuff, it doesn’t work out, but if you didn’t do it then other things wouldn’t have happened, and these other things turn out to be critical to the success of your business.

That’s why you have to go down every rabbit hole.

Chase every opportunity.

Take every meeting.

Give 100% enthusiasm, prepare thoroughly, remain optimistic. 

You never know how things will work out.
