The first thing you learn when starting a new venture is that there are a billion things that need to be done.

It's not good to forget about backups, but if you expend all of your effort on perfect backups then you achieve nothing elsewhere.

In a new venture, you take risks, in this case maybe the wrong risks. But without risk there is no progress. You just can't be 100% on everything, only hope to be 99% on your core competence.

Stop reading the textbooks and try starting a business.
