Develop insights into yourself and the world around you through these scientifically tested questionnaires, surveys, and scales.
Find out where you stand in various areas of life, what you could work on to improve your level of happiness and the personal strengths you can rely on on that purpose.
I particularly recommend the “VIA survey of character strengths”. It is a bit long, yet to know which of your strengths you can rely on to go further in life or overcome hardships is well-worth the time, in my opinion.
I hope you will enjoy and it will prove useful to you. Which one did you find the most profitable to you ?
