What are your good takeaways and useful tips when raising money?

I have come across several statements such as: a single person cannot raise money on their own (you need to be in a team of at least 2 people), it is not worth it because there is pressure on you, etc.

• What is your experience with raising money?

• What did it give you, and who did you raise it from?

• What do you think helped you to a large extent to get the raise?

I would be happy if you would share your short story and your knowledge.
