Effective Self-Help is currently finalising a report into the most effective ways people can purchase productivity. The aim of the report is to synthesise recommendations for particularly (cost-)effective ways anyone can spend money to increase their productivity.
We would greatly appreciate any suggestions you may have for increasing productivity, particularly anything more unique/ less well-known that you've tried. Is there something you pay for that you find highly beneficial to working effectively?
We hope that this report can be added to over time with further community suggestions and function as a master list for anyone looking to experiment with productivity solutions (such as individuals with professional development budgets from their employer).
Our research so far draws on more than 25 previous articles posted here on the Forum, on LessWrong, and elsewhere. We intend to follow this report with research into the best free productivity interventions in the near future. For more info about Effective Self-Help as a project, see our website or this post introducing our work.
Thanks for your help!
EDIT: A quick clarification that the report we're writing aims to synthesise the recommendations from all past Forum, LW, etc. posts on a similar theme into a database that can then be continually updated.
UK/European folks - if you're looking for a second monitor, I recommend you buy one of these. They usually have a discount code, which makes them some of the best value on the market.
The only thing to keep in mind is that they eat up your battery pretty fast, which may not be ideal if you plan to use them for long stretches away from a plug socket.
