When I was a rookie salesperson (phew, what was it, nearly 35 years ago?), I was bereft of confidence. I had the book smarts and the skill to run a half-decent sales call, but I held myself back because I lacked confidence and was riddled with self-limiting beliefs.

And if I’m really honest with myself, I hated that I had to become a salesperson. My goal in life was to become a philosophy professor at Stellenbosch University. I didn’t get a university pass (damn you, maths) and didn’t have a trust fund, so I would not have been able to afford it even if I had gotten a university pass.

Over the years I’ve gotten rid of most of my limiting beliefs, bar one: “I’m not good enough.” You see, I was born into a family with a rich history of intellect and business acumen.

• A grandfather, Senator Bruckner de Villiers, was a Member of Parliament for Stellenbosch, Somerset West, and Barkley East. With Jannie Marais, he founded a small Afrikaans newspaper in Cape Town on 26 July 1915 that you may have heard about: Die Burger.
• Bruckner de Villiers, my father, received his double doctorate in theology and philosophy, summa cum laude, from the University of Zurich, where he also attended Carl Jung’s lectures. Oh, and he had a music degree and played violin for the Cape Symphony Orchestra in the day.
• An uncle, Professor Raoul de Villiers, became Chief Surgeon at Groote Schuur. He was involved with Chris Barnard in the first heart transplant operation. They were good friends until Chris tried to bed my auntie Sugnet. That understandably ended the friendship.

So being a salesperson was not really up to scratch academically. But here’s the kicker. Neither my father nor my uncle Raoul ever made me feel inferior for choosing the life I chose. They were nothing but supportive of me.

It was my perception, and life, after all, is a feat of perception. My inadequacies weren’t real.

How many salespeople feel inadequate because they entered sales after failing to achieve their dream job, like me wanting to be a philosophy professor? And this causes them to have limiting beliefs in their sales ability. Perhaps you feel inadequate too, and would like to stop the negative self-talk in your sales career.

Unchecked limiting beliefs can stifle personal growth, diminish self-confidence, and sabotage achievements. They certainly did for me.

I scratched around the Internet and found the “top 10 limiting beliefs in sales that we face.” Perhaps by bringing them from your subconscious mind into this piece of text, it might help you deal with the hidden limiting beliefs killing your sales.

Let’s reframe these issues positively and develop strategies to overcome sales-performance barriers.

Limiting Belief	Reframe	Action Step
1. Fear of Rejection – “If I reach out, I’ll just get rejected.”	Rejection is feedback, not failure. Each “no” brings you closer to a “yes.”	Make 5 calls/emails daily with a mindset of learning, not winning. Track results.
2. Not Worthy / Imposter Syndrome – “I’m not good enough to sell this.”	You bring value; the client’s problems need your solution.	List 3 tangible ways your product/service helps clients. Review before calls.
3. Money-Related Beliefs – “Making money is greedy.”	Making money enables you to help more people and grow.	Practice stating your price confidently in front of a mirror; role-play with a colleague.
4. Fear of Being Pushy – “If I ask for the sale, I’ll seem pushy.”	Asking for the sale is part of serving the client.	End every conversation with a clear next step or closing question.
5. Fear of Failure – “If I fail, I’m a failure.”	Failure is data; it teaches you what works and what doesn’t.	After each call or meeting, write down one learning point.
6. Belief That Leads Won’t Convert – “These prospects will never buy.”	Every lead is a potential opportunity if approached correctly.	Qualify each lead; focus on solutions, not assumptions.
7. Comparison to Others – “I’m not as good as other salespeople.”	Everyone has a unique style; focus on your growth, not theirs.	Pick one skill to improve weekly; track your personal progress.
8. Perfectionism / Fear of Mistakes – “I must say everything perfectly.”	Mistakes are normal; conversations are human.	Record one call per week to review; note improvement areas, not failures.
9. Negative Past Experiences – “It didn’t work last time, so it won’t work now.”	The past doesn’t define the future; each situation is unique.	Before each call, treat it as a fresh start; use new strategies learned.
10. Fixed Mindset – “I’m just not a good salesperson.”	Skills can be learned; performance improves with effort.	Commit to learning one new technique per week; apply it immediately.

I trust that this article will go a short way to helping you overcome your limiting beliefs in sales. Remember that you are the prize. Your prospects and clients are lucky to have you. You’re giving them something of value, something that can help them build the business of their dreams. Don’t ever forget that.
