Justin Bieber knows that his past does not define him, and he is working on building a better him.

The singer took to Instagram to reminisce about how far he has gotten since some of his toughest times. The singer shared a side by side of his mugshot from his arrest in 2014 and a smiling selfie he took recently and compared where he was then to where he is now.

"I LOVE THIS because it reminds me IM NOT EXACTLY WHERE I WANT TO BE BUT THANK GOD IM NOT WHERE I USED TO BE!! THE BEST IS YET TO COME DO YOU BELIEVE IT?" he wrote in the caption.

In 2014, Justin was caught street racing in Miami and was then arrested and charged with driving under the influence, resisting arrest and driving without a valid license. That arrest produced this mugshot which became widely known on social media mostly because of Justin's big smile.

Justin has come a long way since his run in with the law, and as he said in his photo he might have a long way to go to be the man he wants to be but at least he has changed since then. Instead of street racing, Justin now spends his time with friends and family including going to hockey games with his baby brother Jaxon Bieber.

He shared a photo that looked like they were having a fantastic time together from a Toronto Maple Leafs game this weekend writing: "Btw favourite picture me and my little bro crushing life!"

It is great that the "Sorry" singer is seeing a change in himself and see that he has made so much progress. There is no telling how far he will go and how much better of a person and man he will become in the upcoming years.

To answer his question, we believe in him!
