When wrapping up a meeting where you come to a decision, send an email to all participants.

Be nice to the IT department at work.
They are more likely to quickly help rather than leave you waiting in the queue.

Don't start a tech startup in a tech hub. Run a business completely unrelated to tech and use your skills to improve that business. Go after the low-hanging fruit.
If someone hands you a business card, take a photo of it with your phone in case you lose it.
