I really enjoy this devotional by one of my favorite leadership mentors: Zig Ziglar. The devotional has a Scripture, devotional thought, and then an application challenge at the end.
Ziglar died in 2012 but this reprint of the 2009 edition is just as relevant and powerful. It is a nice devotional to give you that challenge you need to start your day.
For those of you on Tyndale Rewards this is one of the items you can request if you have enough points. If you are not on Tyndale Rewards you should check it out. I have received some great resources from that site.
