In a recent LinkedIn post, Simon Squibb discusses the pervasive nature of self-doubt and how individuals often create limiting beliefs that prevent them from achieving their potential. Squibb uses a compelling anecdote involving a simple pen to illustrate how a fixed mindset can be shattered by a direct challenge and the necessity of action over passive learning.
The core of Squibb’s message revolves around the idea that many of the things we believe we ‘can’t’ do are not inherent truths, but rather assumptions we’ve repeated to ourselves until they feel factual. He recounts a scenario where a woman expressed her inability to sell, describing it as an unchangeable characteristic.
“A woman once told me ‘I can’t sell.’ She said it like it was a fact about her… like her height, or her eye colour.”
Squibb challenges this notion by proposing a simple bet: sell a pen within 60 seconds to a stranger on the street for £100. The woman, despite her proclaimed inability, succeeded in selling the pen with time to spare.
The Power of Action Over Assumption
Squibb emphasizes that his intervention was not about teaching sales techniques. Instead, it was about creating a situation where the woman had to test her own assumption. He argues that traditional advice or courses would have been ineffective because the underlying issue was not a lack of knowledge, but a deeply ingrained belief of inadequacy.
According to Squibb, the only way to overcome such self-imposed limitations is through direct experience. He posits:
“You don’t fix that guess with a course. You can’t read your way out of it. The only cure for ‘I can’t’ is catching yourself doing it… even once, even badly.”
This experience, Squibb notes, was transformative for the woman, highlighting the profound impact of confronting and disproving one’s own limiting beliefs. The brevity of the challenge – 49 seconds – underscores how quickly these barriers can be overcome when tested.
Challenging Self-Perception
Squibb further elaborates on how these assumptions are formed and reinforced. He suggests that we make countless assumptions about ourselves, and the vast majority are not grounded in reality. These assumptions can act as invisible walls, preventing us from even attempting activities that might lead to success or personal growth.
In his view, the key lies in creating scenarios that force an attempt, rather than relying on preparation that never leads to action. He states:
“Sometimes the things you think you can’t do are just things you haven’t tried yet.”
This perspective encourages a shift from passive acceptance of perceived limitations to an active approach of testing one’s capabilities. Squibb concludes by reiterating the unreliability of self-perception when it comes to assessing one’s own potential.
Breaking Free from ‘I Can’t’
The narrative shared by Simon Squibb serves as a powerful reminder for professionals and individuals alike. It advocates for a proactive stance against self-limiting beliefs, suggesting that the path to overcoming them is not through more study, but through the courage to simply try. By creating a deadline and a reason to act, as Squibb did with the pen bet, individuals can begin to dismantle the ‘I can’t’ mindset and unlock their true potential.
