Different streams of income advice?

I'm in a bit of a dilemma financially and have been applying to countless sales jobs since I have a background in that (Did AT&T and T-Mobile Sales) and want to dabble into car sales at like Mercedes.

Hate to rain on your parade but if you've never sold automobiles it's going to be difficult walking into a dealership and being offered a Mercedes sales position.  Unless you've got a 44DD rack.

First thing's first, DO NOT GAMBLE AS A SOURCE OF INCOME.  

Read an intersteung article today about a guy who buys at wal mart sells on amazon. Making a killing.

yeah the people who are doing this are running walmarts business in the ground. Ultimately it will cost more jobs and close stores. Walmart does not like competors. If walmart could they would pass laws against people doing this. Its gotten so bad other big box retailers are closing down stores in rural american in small towns where the jobs and products are needed but you cant tell that to a corporate accountant who is dead set on closing a store and creating a retail space online. Case and point people still go to Blockbuster Video in Alaska to rent dvds
