A picture may be worth a thousand words but adding just a few more, namely a title, description, and keywords, can help you find it even faster.

While dumping pictures and videos is certainly the fastest way to get them into Photos for OS X, the time you save up-front can be more than offset by the time you spend later trying to find a specific picture and video. If you take just a few minutes to delete the pictures and videos that you know you'll never want to see again, and tag the ones you absolutely know you will, you can save a lot of time in the long run. It's a little more work for present you, but future you will thank you!
