I found this quote on Pinterest. And I thought it was absolutely true.
When I was about 12 years old, I had to take a test to determine to which school I had to go. This is a standard procedure in Holland. The result was not so good for me. I could only get the most basic education. My mother was not satisfied with this. To keep the story short; she did not follow my teacher's advice and I finally did the HAVO (a higher professional education). And furthermore, I continued to study in the evenings up to Higher management level and coach of course.
My life would have looked completely different if I had done what the teacher said.
The point I want to make is this: don't always believe what someone else is saying. And there is also a danger in that. If someone tells you all the time that you can't do something. Or that you are not good enough; then there is a chance that, over time, you will actually start to believe that.
If there is such a person in your office, you can do 3 things.
Come on career tiger! You can do it!!
