There are no rules when you give yourself a challenge. You can design it anyway you want. The way you design your challenges affects the way you think about and approach them.
deep challenges are big goals that take more effort than you can map out at once. Their conception and execution is a drawn out process and requires a lot of time thinking deeply, focusing, and working. Each micro goal builds on the last one to create one integrated result at the end.
Shallow challenges are a series of smaller goals that span across a specific time period. Each goal is not necessarily connected to another.
Deep challenges demand consistence through lots of work on one single problem. Shallow challenges also demand consistence through habit-building.
Shallow vs. deep. Blog every day vs. write a book. Make a short video every day vs. make a longer movie. Exercise every day vs. run a marathon.
Use both to your advantage when you’re designing your own challenges.
