Remember: every website you use, every app on your phone, was built by people just like you. There is nothing magical or mystical about technology. Technology is just a tool, and you can learn to master it to solve problems.

If you can see problems in the world, be it not remembering to walk the dog, or being annoyed with washing your car, you probably have an idea for a business. It might not be a billion dollar business, but it will get you thinking.

Get in the habit of starting things. We spend so much of our life planning, waiting, when we should be trying, iterating.
