This world, where much is to be done and little to be known.

Certainty is in much shorter supply than work. You will almost never know enough to act with confidence, and yet the acting still has to happen, which means most decisions get made on partial information for as long as you live. Waiting for the knowledge to catch up is itself a decision, usually a worse one. Doing is where the remaining knowledge tends to come from.

Take the choice you have been researching and set a date to decide, whether or not the picture has cleared. Choose the option you can most easily correct. Then get on with the doing, which will teach you the rest.
