In a time when we are all looking for quick and easy answers to our deep and heavy existential problems I have found quotes to be a neat help to learn and understand complex lessons and in some cases a fast way to get some answers in a swift and effective way. Thanks to the initiative and help of some friends and students I have been able to gather a selection of 300 sentences taken from my books, courses, videoconferences, personal talks etc. I would like to thank all the people who helped me to select these quotes as "most meaningful" for them and as usual with the hope that these quotes might help you in anyway as a starting point to start your own search or a pretext to consider a different point of view, I present you this collection of thoughts that follow my line of thought and give you in just 300 sentences a glimpse and summary of my way of seeing and acting in my life. May this work give you some new ideas or help you to reaffirm your concepts in some way. I wish you the best in your journey and from the bottom of my heart I thank you for allowing me to share my quantum thoughts with you. Decide to be happy NOW.
