Am I Cut Out for a Startup?

I just read a great post by Paul Graham of Y Combinator entitled: "Why to Not Not Start a Startup" that i found through Phil Windley's blog. Y Combinator does real modest seed funding for entrepreneurs (usually less than 20k). Paul says:

So I'm going to list all the components of people's reluctance to start startups, and explain which are real. Then would-be founders can use this as a checklist to examine their own feelings.

He also gives feedback from their first investments back in the summer of 05. Out of 8, 4 were successful - and all that in under 2 years! Not bad.
