Ideally, find great investors
Unfortunately, this last "lesson" isn't always helpful, but if you have options, find the right investor. Finding the right investor makes pitching feel more like having a conversation.
Great investors can see the vision whether you pitch A-to-Z or Z-to-A.
They can spot a stellar team out of a lineup and they know the difference between "dream with me" and focus. To the extent you can, find and work with those investors.
When you go to raise capital, remember to focus on the things that make you a great founder.
