Some people are afraid to try new things because they fear failing. They worry about not succeeding and what others might think of them. If they've had bad experiences in the past, it can make them hesitant to try again. This fear of the unknown can be really strong, and it often comes from not having confidence in their abilities.

Many people prefer sticking to their routines because they find comfort in familiar activities. They feel happy with their current lifestyle and see change as something stressful. Routines give them a sense of security and stability, so they don't want to leave their comfort zone. For them, trying new things can seem like a big disruption.

Some people just don't feel motivated to try new things. They might not see any benefit in doing so or simply lack interest in exploring different activities. With so many responsibilities, they can feel overwhelmed and think that new experiences won't really improve their life. They often prioritize other commitments over trying something new.
