Song lyrics

[tonistuart]

What song do these lyrics belong to and who sings it?

'Finally got my life together,
Put a service on my phone
These days I live the way I wanna
And I do just fine as long as I'm not left alone

I been living it up
\having myself great times
living it up right from the women to the wine
I'm living out all those fantasies i never did get to
Those crazy things I never got to do

Got myself a new persona
My attitude is so much better
And hardly ever cry the way i did before
