If you are designing businesses, rocket ships or websites, some thigns you want to consider.

I like this part:

Everyone on your team is a designer, they just have some different skills than you do. Collaborate.

If you are making things for people who not on your team, include them in the process for making your plan.

Know what “good” means for your product. Then make good products.

I've come to realize that design is not one big thing.

Design is a thousand little things.
