Professional success is not only a matter of technical skill, but also of attitude and behaviour in the workplace.

The mistakes that are killing your career

Small, often overlooked mistakes can accumulate over time and become major obstacles to your career advancement. In fact, some mistakes can end or severely damage your career. 

Here are 10 mistakes that could kill your career:

Insufficient effort: It’s common to become complacent, especially if you’ve been at the same job for years. Yet, pushing yourself daily and venturing beyond your comfort zone can unlock new opportunities, from promotions to pay raises. A bit more effort can lead to exciting career prospects. 

Strategic vision deficit: With a myriad of tasks and coordination demands, it’s tough to pause and adopt a strategic outlook. Nonetheless, grasping your company’s objectives is crucial, enhancing your connection to the organization and revitalizing your professional drive. 

Damaging professional relationships: Maintaining networks and good standing is critical for career progression, particularly within your industry. Alienating colleagues can tarnish your reputation, hindering future job searches. 

Neglecting personal life: Work matters, but without balance, happiness and progress suffer. Carving out personal time is key to overall well-being and career success. 

Merging personal and professional boundaries: Long tenure at a company can blur lines between personal and work relationships. Keeping these separate ensures peak performance and maintains professionalism. 

Chronic dissatisfaction: Job-hopping in search of greener pastures can backfire. Ensure you’re leaving for the right reasons before jumping ship. 

Skill obsolescence: In a world where technology evolves swiftly, staying current is imperative. Outdated skills can leave you behind, outpaced by newer, more adaptable professionals. 

Ignoring intuition: Years in an industry hone your instincts. Trusting this intuition can safeguard against future regrets or doubts in decision-making. 

Overlooking high-value tasks: Rather than spreading thin over trivial tasks, concentrate on impactful projects. These can foster satisfaction and bolster professional development, allowing deeper contemplation of your company role and aiding in your success. 

Self-doubt: Lack of self-belief can lead others to question your capabilities. Rebuild confidence by appreciating your achievements. Dismiss lingering doubts and embrace your worth; you’re more capable than you think.
