Having Fun with Marketing Headaches

Is the glass half empty or half full? Proverbial phrase
Marketing isn't always a bed of roses. It can be stressful, demanding, and raise more than a few headaches...
...but it has its perks, because it lets you experiment, try different things, and keep testing your hypotheses about how your audience will react.
Your efforts always aim to: increase exposure, drive traffic to your sites and assets, raise conversions, boost installs, acquire users, and...it never seems to end.
But marketing is your own vehicle to test every thought and idea, see what works and what doesn't, and figure out how people react to a specific activity, great copy, or whatever you throw at them.
Sometimes you win, sometimes you lose, and sometimes you get just enough data to make a decision forward...which may end up being: "we don't have enough to make a conclusive call."
Marketing headaches will come around frequently, and you keep trying to solve them, simplify so you can multiply, and either grow or let off steam before moving on to the next campaign or effort.
Knowing this cycle never ends can be frustrating. But it can also be incredibly freeing: it proves the whole thing is just a cycle, and that you need to go through the motions to arrive at some decision forward based on results. It also tells you that you won't be able to break it, so why not embrace it like a pivot and keep trying new things and new ways to achieve your goal?
In other words: doesn't this mean you have a license to have a lot of fun? Doesn't it demand that you try out new things and new ways?
...so don't you think you're actually pretty lucky in marketing?
