When I was at the beginning of my career they all said to ‘plan your career’ and go with that plan. Nothing could be further from the truth. A career is not plannable for the long-term, perhaps for the next 1-3 years and the next move yes. But my career has taken so many twists and turns, this I could never have foreseen.
Rather I wish they had told me it is important to have adaptable skills like flexibility, ability to learn and to adapt, communicating with different personality types and so on. Plus the critical importance of mind-set/attitude.
