regression - second chance at life

Adam's life has been a huge disappointment.
Growing up, he was a shy kid with no confidence; he had no ambition; he had no plans for the future.
He didn't realize the time flowing by until one day he hit rock bottom.
His wealth was taken away from him. He had nothing.
Now he lives in a single-room apartment, he is making barely any money; he has no friends, no family, and no lover. He is all alone living a pathetic, miserable life.
He is so pathetic that he died in his own apartment, slipping on a beer bottle.
But fate has other plans for him. He didn't die but ended up back in the past with an upgraded body.
Now, with another chance in life, he is determined to strive for greatness.
