Washington(CNN) Barack Obama continues to have hope.

The former President took to Twitter on Friday to share some stories he said "remind us what's best about America."

"As we count down to the new year, we get to reflect and prepare for what's ahead," he tweeted. "For all the bad news that seemed to dominate our collective consciousness, there are countless stories from this year that remind us what's best about America."

In his tweet thread, Obama shared a news article about Kat Creech, a wedding planner in Houston who turned a postponed wedding into a volunteer opportunity for Hurricane Harvey victims.

He also tweeted about Eagles defensive end Chris Long giving his paychecks from the NFL season to fund scholarships in Charlottesville, Virginia, and Jahkil Jackson, a 10-year-old who created kits full of socks, toiletries and food for homeless people in Chicago.

He concluded at the end of his thread: "All across America people chose to get involved, get engaged and stand up. Each of us can make a difference, and all of us ought to try. So go keep changing the world in 2018."
