What should you create? It depends on your skills, interests, and personality. If you are analytical, you could draw on a group of articles you’ve read about Big Data to write a blog post summarizing where you think machine learning is headed next. If you like to perform, you could borrow ideas from your notes on YouTube cooking videos you’ve enjoyed to make one of your own. If you are campaigning for investment in your local park, you could distill the minutes from past city council meetings into a speaking agenda for your public comments at the next one.
