People very widely as to whether or not they would want to work at home. Many have tried it and never went back, and others couldn't stand it or couldn't be productive and went back to the "office" way of doing things. It really depends on what kind of a person you are and whether things like freelance data entry jobs are for you.
Some people are self motivated, able to concentrate on the task at hand (whether it be eating a burger or doing data entry jobs) despite very accessible distractions, and are disciplined enough to make a regular schedule that allows them to be very productive while not allowing themselves to be imprisoned--never able to escape their job which is always right there. Others need a change of scenery, need extra motivation slash accountability that working with coworkers brings, feel isolated, or just don't plain enjoy their house enough to be at home all the time. This is more of an old-fashioned--off to the factory--mentality.
How hard is it for you to do the normal things of life like go to the bank, doctor, etc.? If you are like most it is next to impossible because there are only so many personal days and the typical 40 hour week is inflexible and unyielding. You see there are too many amazing benefits that come with data entry jobs that allow you to work from home and flexibility is the most valuable one of them all. So first major benefit, you get to stay healthy and on top of your money.
Next benefit of this amazing flexibility is that you can take breaks when you want to. When I say breaks I mean breaks as in vacations which are very necessary to your health as well. Think of it this way--working from outer space is almost the same as working from Europe (or data entry jobs, you choose!). Last major benefit is dress code, or lack thereof. Don't get me wrong if you would rather work in a stiff white shirt and tie than luxurious soft sweat pants than you can!
Unfortunately only the first and not the second group of freelance data entry jobs are able to enjoy the amazing and unique benefits of working at home that are there to take advantage of. So stop your boring job in the cubicle and get on board with the rest of us internet jockeys and work as you will. Fortunately, as this world becomes more linked globally through the wonders of technology, this second group of people (those who cannot work from home) is becoming the minority. You will wonder why you ever did it any different.
