Before getting efficient, first prioritise effectiveness. Efficiency allows you to do some- thing quickly and well, but effectiveness determines what you choose to do in the first place and how well you do it. It’s no use being hyper efficient at a task that has little to no effectiveness when it comes to achieving your goals. Decide on what is effective first. And carrying out a dry/quick-&-dirty/rehearsal version of the task, be it a draft, a sketch or a prototype, will help immeasurably with the quality and effectiveness of your final output. No one gets it 100% right the first time.
