What factor is identified as one of the greatest impediments to meeting new people?

The factor identified as one of the greatest impediments to meeting new people is routine. Routine encompasses the daily habits and predictable patterns individuals often fall into, which can limit their exposure to new social environments and opportunities for interaction. When individuals adhere too strictly to their routines, they may miss chances to engage with others, attend new events, or explore different social circles. Breaking free from habitual behavior allows for greater openness to forming new connections and seizing social opportunities.

Procrastination may delay actions but does not inherently restrict social interactions as much as being stuck in a routine can. Laziness implies a lack of desire to engage, which is more about motivational issues than structural limitations. Shyness is a personal characteristic that affects one's willingness to approach others, but it doesn’t directly reflect the broader limitations imposed by daily routines. Therefore, routine stands out as a key factor that prevents individuals from expanding their social networks.
