Branson recalled a recent time he was in South Africa speaking with the manager of one of his properties. As a result of not taking down notes during their conversation, the manager failed to take action on what he and Branson had previously discussed.
"If you don't write things down it's really easy to forget what was said – and often in business, it's the little things that make a big difference to your customer," Branson said. "Keep a notebook in your back pocket to scribble down thoughts or feedback and make sure you follow through on them in a timely fashion."
Branson said he has always made lists of things he wants to achieve as it helps him make sense of his ideas and track his progress.
For 2018, Branson's goal is to continue preparing for his space travels through his company Virgin Galactic, according to the post:
Get unbelievably fit so I'm ready for a trip into space. I'll be doing lots of trekking and biking to get me into top shape. When I finished the Virgin Strive Challenge in 2016 I felt like a 25-year-old again – I hadn't felt that good in 40 years. I'll also be doing some centrifuge g-force training so I'm as acclimatized as I can be for the journey.
While sharing your goals with your family and friends is helpful, Branson noted it's ultimately up to you to follow through. Another trick to making goals is to set both short-term and long-term ones so you can feel a sense of accomplishment along the way, Branson wrote.
"If you set daily goals and work through your list every day, you can mark off every completed task with a satisfying tick," Branson explained. "This helps keep you motivated to aim for the big targets."
That "satisfying tick" is one way Branson recommends that you "celebrate all the little wins," but more importantly, continue writing more lists after you meet your goals.
"No matter how big, small, simple or complex an idea is, get it in writing. But don't just take notes for the sake of taking notes, go through your ideas and turn them into actionable and measurable goals," Branson said.
