On Friday, we told you about the day-long "Startup School" held at the University of California, Berkeley on Saturday. Given the caliber of speakers, we thought it might be a good place for journalism entrepreneurs to learn a few tips and tricks.

Here are seven lessons from the sessions:

1. Be clear about what you're trying to do

"Not having a clear goal leads to death by a thousand compromises." -- Mark Pincus, Zynga co-founder (courtesy of Gabor Cselle, Gabor's Positive Thoughts)

2. Remember your user

"One thing we commonly see is startups with fabulous technology, but inability to clearly describe, 'who cares?'. Need to show there is market, people who will spend money on this product. Describe in business terms why people care." -- Greg McAdoo, partner, Sequoia Capital (Transcribed by Jason Kincaid, TechCrunch)

More, after the jump

3. Don't wait for your project to be fully baked

"Launch early and iterate; Facebook is a really good story of that." -- Mark Zuckerberg, Facebook founder (From AFP)

4. Choose your colleagues wisely

"It's hard to pick which companies will be successful, but you can choose to work with smart people. That's probably the best heuristic." -- Paul Bucheit, Gmail creator, FriendFeed co-founder (Transcribed/Paraphrased by Kim-Mai Cutler, VentureBeat)

5. Work on the ecosystem (not just your project)

"We want to keep expanding the platform, helping the ecosystem. A lot of the value for Twitter comes from third party [developers]. We're bolstering our platform team (both engineering and dev support side)." -- Evan Williams, Twitter co-founder (Transcribed by Kincaid, TechCrunch)

6. Recognize when it's not working

"I have this one friend [who has] some harebrained idea for a startup. And they keep sticking with it, and think if the world doesn't see it, they will one day. They confuse stubbornness with great entrepreneurship.... You should give your five to seven friends a pitch. Ask them if they want to buy stock in that company... use that as your sounding board." -- Pincus (Transcribed/Paraphrased by Cutler, VentureBeat)

7. You've got nothing to lose. Really.

"The biggest risk you can take is to take no risk. In an evolving world, if you don't change you lose." -- Zuckerberg (from AFP)
