To simplify the expression, first evaluate the numerator:

1/m - 1 - m + 1/m^2 + m + 1

Combine like terms:

= 1/m + 1/m^2

Now, evaluate the denominator:

(1 + 1/m^3 - 1)

Simplify:

= 1/m^3

Now, substitute the evaluated numerator and denominator back into the expression:

(1/m + 1/m^2) / (1/m^3)

To simplify further, divide the numerator by the denominator:

= (1/m + 1/m^2) * (m^3/1)

= (m^3 + m) / m^3

Therefore, the simplified expression is:

(m^3 + m) / m^3
