"Don't waste your time with explanations: people only hear what they want to hear." 
"There will be a few times in your life when all your instincts will tell you to do something, something that defies logic, upsets your plans, and may seem crazy to others. When that happens, you do it. Listen to your instincts and ignore everything else. Ignore logic, ignore the odds, ignore the complications, and just go for it."
