About Sebastian Sauerborn

Founder & CEO of Mount Bonnell Advisors

For the past decade, I have been speaking to hundreds of European and American entrepreneurs every year.

This has allowed me to identify one particular trait that almost all of my interlocutors shared in common:

Entrepreneurs have a sixth sense for the incomplete, the unfinished and the yet-to-be-accomplished. For tasks that are still in the process of being finalized. For the job that is still right in front of them. For work in progress.

These entrepreneurs are experts when it comes to spotting shortcomings. They have a precise vision of the future in front of their eyes and are simultaneously able to realize (sometimes painfully) how much the actual situation deviates from it.

However, this “negative entrepreneurial spirit” also has a flipside: These entrepreneurs tend to only see the flaws. They are inclined to perceive all of life itself as a never-ending work in progress. And sometimes they might even feel that “nothing is working right”.

Does this description fit you?

I view the trust, which entrepreneurs instill upon me as part of my consulting activities, as a special privilege. It is this trust that allows me to point out new perspectives and share past experience, which the client can eagerly open him or herself up to.

An important impulse that I want to impart along the way is gratitude and an awareness of what the client has already achieved — and also that which he or she has received without any effort of his or her own.

Our focus is the entrepreneurial strategy for a profitable future. The future doesn’t just “happen”, however. It cannot be viewed as isolated from the past. The future has its foundations in the hard work that already lies behind you, in what you have already achieved in your life and as an entrepreneur.

Gratitude for a successful future is also something that you owe to those who have accompanied you along the way and who have made this future possible in the first place: parents, friends, spouses, children, teachers, grandparents, colleagues… All of those who have put up with you and who believed in you. Those you loved. Those who were there for you. Those who listened to your crazy ideas. Those who made time for you. Those who helped you up and supported you that time when things didn’t work out and you were on the bottom.

The most successful and luckiest entrepreneurs who I’ve had the chance to meet were in no way perfect. Neither in their daily business affairs nor in family life. But next to the constant pressure and tension, I could also see a sense of gratitude, which, in turn, resulted in the making serious efforts for the sake of the people around them.

I hope that both you and I gain this ability, too!
