Fourth, you can bundle your eBook with other goodies in order to bump up the value and make it more unique. With so many advantages, it's worth putting up the time and start building your own platform.

These deductions are allocated for the next tax year and are applied in a reasonable manner that takes into account the next year's earnings or losses.
