Apollo Nida from 'Real Housewives of Atlanta' has decided to post some encouraging messages over Twitter, right before he begins his prison stint.

Nida reportedly tried to finish a tell-all book before he begins his incarceration, which is scheduled to start on Wednesday, September 10. Nida is set to to serve an 8-year sentence for charges of fraud.

A source told TMZ that he is working hard to finish his autobiography. He is working with a team of writers to get this book done which will focus on the different facets of his life that most likely led him to spend time in prison. On a side note, he's even ready with the book cover photo.

A few days before, he posted some positive words of wisdom to his Twitter followers.

The tweet reads, "GOOD MORNING TO ALL!! YES EVEN TO THE NEGATIVE ONES.."

Then, there is another tweet that says, "THANKS 4 ALL THE SUPPORT & KIND WORDS. WE MUST LEARN TO HAVE A LIGHT HEART."

Apparently, this bright-sided trend started a week before, when he posted a greeting to his followers, "Hello I hope everyone is doing well."

These tweets are a complete turnaround from what he was tweeting back in July just after he was sentenced to prison. During that time he posted, "Question?? DOES ANY-1 HAVE ANYTHING POSITIVE TO SAY WTF!!!!"

There is little insight floating around as to why Nida had a change of heart, but one thing is for sure, this prison stint is surely going to be a difficult time for him and his family.
