You might think that working as a blogger full time has just endless benefits, but there are negatives to that as well.  Many benefits you’ll get at any typical full time job, you often won’t get as a blogger (that is if you work for yourself).

The Negative Side to Working as a Full Time Blogger
Unpredictable – Though usually traffic is steady, strange things can happen, like getting banned from Adsense which can take a good chunk out of your paycheck.
No Unemployment Benefits – If you somehow lose your blog due to hacker, deindexed from Google, etc, you won’t have any unemployment to be able to claim.  Make sure you have a large amount of savings to fall back on.
Suclusion – You find yourself working alone day after day in a little office.  You miss out on the socialness that working  in an office brings.
Future? – You might have no idea what the future will bring.  The internet could be going in any direction.
