Short term gains can be highly useful for a lot of people as long as they are implemented correctly, and it is this implementation process that will aid you in all of your endeavors no matter what these endeavors might end up being.

These kinds of gains are what will legitimately allow you to make the most of your work by earning a steady income from the get go rather than having to wait for one of your long term goals to finally pull through and give you some much needed cash coming in.

Staley, and it is by far the best book that you will ever be able to read on this subject due to its detailed analyses and concise writing style.
