Many software developers (the ones that haven't been in on a start-up usually) are tempted to make the jump into the seemingly glamorous start-up world to build that next killer web app. Keith Casey has posted a bit of a reality check for developers thinking of making the move.

In the last few weeks, I've talked with a number of friends about career changes. Some are feeling antsy and just want to move, others are starting their own consulting, and others are starting and joining startups. While I've done all the above - to varying levels of failure success - I thought I'd share the things I've learned along the way.

He gives six things to keep an eye out for when considering your entry into the startup world:

• Everyone does everything
• There's no career path
• You never have enough money
• v1.0 never looks like the original Vision
• Every founder believes in him/herself
• Most startups don't explode, they fizzle

He's not saying all of this to push you away from startups, though - more to help you go in "with eyes open" and ready to ask the harder questions before you get into a bad situation.
