+# Goals
+
+"Bad goals are indistinguishable from numbers." - Will Larson
+
+Good goals are made up of 4 specific kinds of numbers:
+
+1. A target - where you want to go
+1. A baseline - where you are now
+1. A trend - your current velocity
+1. A time frame - the bounds for the change
+
+The tests for a good goal are:
+
+1. Someone that doesn't know the details of the project can tell its difficulty.
+1. Someone that doesn't know the details of the project can determine if it was successful.
+
+## Investments and baselines
+
+An investment describes where you want to be in the future, a baseline describes what you have now that you want to keep.
+
+It is often a great idea to pair investments with baselines in your goals to help narrow the scope you use to find a solution. Baselines can also be useful in identifying when you should pause on an going after a goal and instead invest in platform quality.
