Success/failure begin to occur the very minute you begin to do what you really want to do in life. If you do not know what you want to do, find out what the world needs and work to fulfill that need. Overcome your personal problems, embrace failure, but take further action now. Stop waiting for miracles to happen. Make miracles happen now. There are only so many tomorrows.
Edison overcame his hearing impairment while inventing light bulb, motion picture camera, stock ticker, X-ray machine, and many others. By the time of his death in 1931, Edison held over 1000 patents – all because he embraced failure. Errors, and failure are necessary on the path of discovery. Each time you fail, you eliminate another way that will not work.
