It’s a blessing but also a curse. The fear of missing out is often characterized by over-commitment. People who are on a regular search for excitement, or scared of missing out on any opportunity to grow or feel good definitely have a very exciting and adventurous life. If it is done in moderation it can absolutely benefit, but always seeking for a thrill and at the same time feeling like your life is not good enough can lead to serious dissatisfaction and unhappiness. You have to be clear about your values and goals, and set your boundaries in alignment with those.
