The last 10% is 90% of the work.
Focus is saying no to 1,000 good ideas.
[Oprah Winfrey said in one of the interview she was giving :]
"There’s a wonderful phrase by Maya Angelou, from a poem that she wrote called “To our grandmothers”, that she says:
“I come as one, but I stand as ten thousand.”
So when I walk into a room, particularly before I have something really challenging to do, or I’m going to be in a circumstance where I feel I’m going to be you know, up against some difficulties. I will literally sit, and I will call on the 10,000."
Note : the actual phrase in the poem is : "I go forth along, and stand as ten thousand."
I'm convinced that about half of what separates the successful entrepreneurs from the non-successful ones is pure perseverance. It is so hard. You put so much of your life into this thing. There are such rough moments in time that I think most people give up. I don't blame them. Its really tough and it consumes your life. If you've got a family and you're in the early days of a company, I can't imagine how one could do it. I'm sure its been done but its rough. Its pretty much an eighteen hour day job, seven days a week for awhile. Unless you have a lot of passion about this, you're not going to survive. You're going to give it up. So you've got to have an idea, or a problem or a wrong that you want to right that you're passionate about otherwise you're not going to have the perseverance to stick it through. I think that's half the battle right there.
