Who can resist the dinging sound of a new email? You, that’s who, especially if you want to stay on task. And forget about signing in to Facebook “just for a minute.” It’s easy to get distracted when you telecommute—unlikely distractions that just don’t exist at work abound at home. At the office, for example, you might visit the company kitchen once in the morning and once in the afternoon for a cup of joe (because that’s what’s appropriate), but at home, you’re hitting the fridge every hour on the hour. Or more.
There are actually more deals out there like this than you'd believe, thanks to the fact that sellers list used textbooks for low prices on Amazon all the time, not realizing they could trade that book into Amazon for more money. For example, you might see a Biology 101 textbook that has a used price of $45 and an Amazon trade-in price of $70 – meaning you could buy it and trade it right back in for about a $25 profit.
Don't use jargon. If you are offering technical expertise, include descriptions that appeal to your client base, not your peers. For example, if you are showing that you can code with PHP and AJAX, don't say "in this case, if the input field is empty (str.length==0), the function clears the content of the txtHint placeholder and exits the function." The person who needs you to work on their site will just scratch their head and say "huh?" Say, instead, "Start entering text into this field, and it will auto-complete."
