As a startup founder， my daily tasks include everything from long-term strategic planning to approving team outings and company culture initiatives. Day after day， things inevitably come up that need to get handled ASAP. But l've also learned that if you don't have a strategy for making time for those bigger ambitions and your truly lofty goals， they'll simply never get done. And that means you won't make the progress that's really going to move your business forward.1） FIND YOUR MOST PRODUCTIVE TIMEFace it. You aren't cranking out work at absolute peak productivity for the entire day. Instead are likely certain times when you are at your most focused and other times when your energy wanes. That's normal. Maybe for you， it's bright and early in the morning， before anyone else arrive in the office， when you do your best work. Whenever it is， identity that when you feel your most productive， and then reserve it on your calendar like you would any other important meeting. You need to protect this block of time from intrusion-it isn't optional. That way you're guaranteed to have a regular， designed period when you can at least on those bigger to-dos.3) According to paragraph 2， which of the following the "chunk of time" the author is talking about?
