I am fairly sceptical about personality questionnaires and models.
However, they do have one big benefit. As you answer the questions and then evaluate your profile at the end, you're pushed to reflect on who you are, how you think and how you act.
And this reflection can be the trigger to do a little work on yourself so that you can become the best versions of you.
So, if you would like to invest 5 minutes to reflect, here's a link to a quick, 30-question survey based on the Big Five Model (generally accepted as the most robust of all the personality models).
[note: if you get to the end and don't immediately see your report, scroll back up and make sure that your response has been recorded for every question]
