Morning Motivational Email to Text

Dec 29, 2014 php
This post is more than 18 months old. Since technology changes too rapidly, this content may be out of date (but that's not always the case). Please remember to verify any technical or programming information with the current release.

So I’m going to try this new thing - watch a motivational quick movie in the morning via youtube. I made a playlist of videos and have put the following code in cron for 5:30 every morning. It will send an email (which is actually email to txt on my phone) with a link to open the youtube player on my phone with a random item from my playlist. Hope you find it useful!
