The Reincarnation of the Greatest Talent TRGT

Him who became the worlds greatest talent died in a unfortunate way.

Spencer Brady had always been the best in whatever he sets his mind to from a young age. At 10 he had solved a formula which had become a headache for mathematicians for centuries. At 14 he graduated Harvard becoming the youngest person to graduate from there. At 17 he became millionaire after he successfully developed a new software. At 20 he becomes a billionaire after developing the latest technology and establishing a company.
He seemed to be able to do whatever he put his mind to except for one thing ...
He was never able to see through the women he loved. One day when he came from work he found his beloved and his best friend in bed. He immediately tried to divorce her but it was too late. All his property and his bank accounts were no longer under his name. The same day Spencer went to divorce her, his former best friend sent a group of assassins to kill him.

Spencer die with so much regret and sorrow that he implored God for a second chance in life. After Spencer woke up he realized he traveled back in time to the day he solved the math problem and became known as a prodigy.
Now knowing what will happen and who not to trust he sets up once again to become wealthy again but choosing a different route.

How will Spencer live this life? Did he learned from his mistakes? What will he do now?
