Isabelle Gonnissen is the driving force behind the successful campaigns of '30 Days Without Complaining' which have inspired over 2 million Belgians.

Why should you choose a positive mindset? A positive mindset allows you to face challenges and obstacles with an optimistic and solution-oriented attitude, attract positive opportunities and experience more happiness and fulfillment.

Let a sparkling keynote motivate you to complain less, live more consciously and positively so you can be in your power and be happier.

Isabelle gave us a very inspirational talk about '30 dagen zonder klagen'.. a lot of useful tricks and tips how to succeed! Even if 30 days seems hard to achieve, doing a little bit day by day for 30 days will already make a big difference. Thank you very much Isabelle, keep inspiring other people.
