2. Living in a bubble
Many smart people often live isolated lives without a lot of real friends or meaningful connections with other people. This is because they get so focused on the job or project that they are working on that they often forget to slow down, take a step back and enjoy the things around them. This definitely can lead to some great work being done however when speaking to many of these smart people later in their lives they often regret not spending more of their time with their true friends and family.
