Action will get you results - true But if you don't plan AT ALL (even for 1 minute) there is a high chance you will end up with some results, which is good, but: - you might not be able to repeat them (because you did a lot of shot without any plan and can forget things) - if you can't repeat you results, you won't be able to get bigger higher results on top of what you have gotten in the first place - and if you can't improve you results, you will be running in circles So plan at least somehow: - on a napkin - on a piece of paper - write the plan on your hand - make it up in your mind It can be just 3-5 steps, but please DO TAKE SOME TIME FOR PLANNING, before action And to answer your question. You gotta do both, because one without the other won't get you far, and won't lead to consistent success
