On his advice to founders
Find a good partner.
Don't listen to too many different voices, especially from people who aren't seeing the results of that advice.
Drive-by advice is not great, considering the fact that startups are about iteration. You want to try something, see results, and continue to adjust.
That's why for us at Science, the studio model works best because the advice we give gets adjusted because we see the results in real-time.
Overall, move quickly but don't hurry. Startups take a while to figure out.
The highs are high, the lows are low, and it's important to remember everything will take longer than you expect.
Make sure you prioritize your work appropriately, accounting for the harder tasks you may have to do in the near future.
For anxiety and stress, make sure you take some breaks and lean on your team more to take care of things without you. Don't micromanage.
