Urgency is a myth, so before you start taking action, make sure you understand what you are acting upon.
In marketing, for example, it is very easy to fall in the trap of doing. You start a new job, there is a pressure to get more visits to the website, more content, more leads, and so you begin with tactical actions already on your second week on the job (if you have been good enough to last that long). You do not know anything about the customer, very little about the product, even less about your colleagues, what they do, what their challenges are, and why you are in the job in the fist place.
No wonder many are dissatisfied with their marketing efforts. There is a reason if tactics, channels, messages change all the time, while strategic marketing is essentially the same from decades. Start with the basics, make sure you clearly understand who you are serving (internally and externally), and what you can do for them. Where they are found, why they should care, whether there are alternative solutions to their pains and why yours is better.
If your boss does not understand that, you might be in the wrong place. You need to build solid foundation if you want to build anything that stands the test of marketing fads.
