Many people in EA value personal productivity highly, and make it a goal to complete as many tasks on their to-do list as possible in a day. Some people (myself included, in the past) seem to tie up their feeling of self-worth with how productive they felt that day.
I think that increased productivity should mainly be used to reduce the amount of time we work each day, and not to get more things done. To live a truly fulfilled life we need more unstructured, unproductive time when we can be ourselves and do the things that we find inherently valuable and enjoyable.
Here are some things that I find valuable in themselves, and not particularly productive:
Running along a river or canal in the morning
Reading a history book in a café
Listen to classical music on the radio
Prepare an elaborate dinner for my girlfriend
Try all the different types of cheese from my local shop
I think productivity is highly emphasized both within EA and within the wider society, especially in the context of work and studies. There is not nearly the same amount of emphasis placed on unproductive downtime and its value for our mental and physical well-being. I think that if most of our productive "output" comes over a long-term career, we need to value our own time more.
Another way of thinking about it is that being highly productive is not in itself a virtue, a bit like driving 150 km/h on the highway in a random direction doesn't necessarily take you to where you need to go! So I would say its probably better to be driving a bit slower and taking lots of breaks along the way to check that you are going in the right direction.
