Steve Jobs shares three stories from his life in his 2005 Stanford commencement speech:
1) He dropped out of college after 6 months but took a calligraphy class that influenced Apple's graphic interface. This shows the importance of trusting your instincts and that opportunities come from unexpected places.
2) He was fired from Apple at 30 but it allowed him to start NeXT and Pixar, find love, and later return to Apple. Getting fired was the best thing that could have happened.
3) Facing death from cancer diagnosis, he recommends living each day as if your last to focus on what's important - family, work you love. It helps avoid fear and follow your heart.
