Happy Valentine’s Day to the extraordinarily smart, beautiful, funny, one and only @MichelleObama. It’s true; she does get down to Motown. https://t.co/uypbZsEiqB

In the year since their friends were killed, the students of Parkland refused to settle for the way things are and marched, organized, and pushed for the way things should be - helping pass meaningful new gun violence laws in states across the country. I'm proud of all of them.

Don’t be sad it’s over, be proud it taught us so much. Congrats to all the men and women of @NASA on a @MarsRovers mission that beat all expectations, inspired a new generation of Americans, and demands we keep investing in science that pushes the boundaries of human knowledge.

Happy 85th birthday to @RealBillRussell - the greatest champion in American sports, and a lifelong warrior for justice.

My statement on the passing of former Congressman John Dingell: https://t.co/gjBYHHImzB

We lost two great Americans today – Frank Robinson and John Dingell – citizens who inspired me and so many others by leading on the civil rights issues of our time, opening doors to others, and leaving it all on the field.

As we celebrate Black History Month and Jackie Robinson’s 100th birthday, we celebrate the life of all whose courage opened the gates for everybody, and in the process, made America better. https://t.co/Fl9aDxqcGi

The @ObamaFoundation is connecting people from around the world so they can form partnerships just like this. I am inspired by Robert and Vanessa and what’s possible when leaders come together to have an even greater impact on the world. https://t.co/hFAMzW7tBq

I’ve always drawn inspiration from what Dr. King called life’s most persistent and urgent question: "What are you doing for others?" Let’s honor his legacy by standing up for what is right in our communities and taking steps to make a positive impact on the world.

RT @MBK_Alliance: President Obama challenged us to improve our communities in 2019—and mentorship is a concrete action we can take. With @MENTORnational, we’re expanding mentoring across the U.S. On #InternationalMentoringDay help a young person reach their full potential: https://t.co/fQa6JA0CAw https://t.co/yDepiRGhuH

I knew it way back then and I’m absolutely convinced of it today — you’re one of a kind, @MichelleObama. Happy Birthday! https://t.co/ejqm0uC9J4

In 2018 people stepped up and showed up like never before. Keep it up in 2019. We’ve got a lot of work to do, and I’ll be right there with you. Happy New Year, everybody!

I hope you find inspiration in the stories of Dejah, Moussa, Sandor, Hong and Jonny. Their journeys began with a decision to build the better future they wanted to see. The same is true for you. What matters isn’t the size of the step you take; what matters is that you take it.

Leaders like Jonny Boucher, a Chicago native who, after losing too many friends and family to suicide, started a coffee shop to offer emotional support and guidance to those who might be in need of a little more than a strong cup of coffee to get through their day. https://t.co/H6XPceR6d9

Leaders like Hong Hoang, who mobilized a youth-led movement to create a greener world after becoming the first Vietnamese person to visit Antarctica. https://t.co/K8xPNC1OCQ

Leaders like Moussa Kondo and Sandor Lederer, who are each doing their part to fight corruption in their native countries of Mali and Hungary. Two people separated by continents but united in their pursuit of a more just, transparent society. https://t.co/YbOxSEyyCd

Leaders like Dejah Powell, who started an organization to bring health and wellness resources to communities on the South Side of Chicago, expanding food access and providing people the space and time to take care of themselves. https://t.co/tPW7NxTGLO

As the year winds down and we look toward 2019, I’m asking you to make a commitment: find something you want to change in your community and take the first step toward changing it. If you need some inspiration, take a look at some of the young leaders who inspired me this year.

As 2018 draws to a close, I’m continuing the tradition of sharing my year-end lists. It gives me a moment to reflect on the year through the books, movies, and music that I found most thought-provoking, inspiring, or just plain loved. I hope you enjoy it: https://t.co/qz6TCMKnkL

Enjoy the holiday season with the ones you love. Michelle and I wish you a very Merry Christmas! https://t.co/LKLqlYfFUw
