From the article: 

"It’s easy to get into the 'if only' mindset when you’re the only marketer at your company, but if you want to grow your business, it’s important to shake it off and get solution-oriented. Instead of having an all-or-nothing attitude, try to focus on getting the most bang for your buck from every marketing activity you can muster the time and resources to execute. That means recognizing that not all marketing tactics are equal -- some may take you forever to execute and have little reward, while others, with a small tweak, could have a huge payout."
