Miller found her way into the field through overcoming a battle with bulimia in her early twenties, and in the decades since, has leveraged her experience and education as an executive coach and bestselling author, including her most recent title,

麻豆社 sat down with Miller to unpack some of the widely held misconceptions when it comes to setting and achieving goals 鈥 including ambitious New Year鈥檚 resolutions 鈥 and the strategies that are more likely to lead to success. 

鈥奙ost people fail at goals because they set goals in isolation.

First, people often think they鈥檙e incapable of achieving their goals because they lack discipline or willpower, but that鈥檚 typically not the case. 

鈥溾奙ost people fail at goals because they set goals in isolation and they don’t take into account energy, emotion, relationships, the use of character strengths,鈥 Miller explains, 鈥渙r even this powerful finding in 2005, that all success is preceded by being happy 蹿颈谤蝉迟.鈥&苍产蝉辫;

According to Miller, being in an emotionally flourishing state, which encompasses positive emotions like contentment, satisfaction, love, joy and more, is 鈥渢he rocket fuel for achieving goals.鈥&苍产蝉辫;&苍产蝉辫;

Additionally, people make the mistake of thinking they need to set numerous goals at once 鈥 including too many that involve willpower.

鈥溾奩ou have to usually pick one,鈥 Miller explains. 鈥淭he research shows that when you isolate a willpower goal 鈥 lifting weights, losing weight, quitting smoking, reining in your spending 鈥 [and] work on one area, it tends to spill over into another area of your life without you even focusing on it.鈥 

Most goals are not specific enough.

It鈥檚 also helpful to avoid setting goals that are overly vague or open-ended; the 鈥渏ust go out and do your best鈥 mentality is often too imprecise to translate into real results. 

鈥淕oal-setting theory says it has to be challenging and specific to get the best outcomes,鈥 Miller says. 鈥淢ost goals are not specific enough.鈥

What鈥檚 more, people should try not to fall into the trap of thinking they鈥檝e done more work toward their goals than they really have. It鈥檚 why the common advice to 鈥渧isualize your success鈥 can actually backfire. 

鈥溾奩ou can’t hit a target you can’t see,鈥 Miller acknowledges, 鈥渂ut then you have to come back to where we are today. It’s called mental contrasting. Say, What are the obstacles that are going to be in my path that I have to have strategies to overcome?

鈥奍t’s really important to be surrounded by people who have zest.

Seeking out people who are a positive influence 鈥 and want the best for you 鈥  can help pave the way for success. 

Make sure the people in your circle are curious and enthusiastic about what you鈥檙e doing and how you鈥檙e doing it, Miller says. 

鈥溾奍t’s really important to be surrounded by people who have zest, who have optimism about their future because it’s a contagious quality,鈥 Miller adds. 鈥淚t’s a contagious behavior. Even grit is also considered contagious because it’s small decisions and behaviors that actually cause someone to do a little bit more than someone who quits.鈥

As valuable as it is to have people cheering you on, it鈥檚 also important to have those who challenge you, too, Miller says.  

Miller points to Katie Ledecky, the swimmer who is the most decorated American woman in Olympic history, and who happened to grow up around the corner from her, as an example of what happens when the people around you support your goals 鈥 but also push them further.

When Ledecky was in eighth grade, before she鈥檇 even competed outside of the country, her coach asked her what the best thing she could achieve in the coming year would be. Ledecky said making the Olympic team, and her coach encouraged her to think of something harder 鈥 something even better.

鈥淗e challenged her because he knew her capacity for hard work, and he saw greatness in her in a way that she didn’t see in herself yet,鈥 Miller says. 鈥淲hen you’re going to pursue goals, particularly hard goals, you want people who are going to challenge you because they might be able to see something you’re capable of doing before you can see it.”
