I am happy with comfort zones

I am tired of listening to people that I need to challenge myself and move out of comfort zone.. Go challenge learn a new skill, play a guitar, or go start networking or partying, I am an introvert become an extrovert, go take a holiday alone and discover new places, make a new set of friends, change role as you are doing well in the role means you have learnt everything possible, find a girl for yourself you getting comfortable with self.. blah blah blah.. 

The amount of advise I on this from family and friends is unthinkable, the only silver lining is I am not alone.. Almost everyone gets it and there is enough written by experts that how comfort zone means I am a big loser :(. In fact I am better off as I don't indulge in self flagellation, this friend I was speaking to on the topic feels guilty as she is acting in accordance with comfort zone...

My argument is what's wrong with comfort zone? We chase happiness that's the meaning of life and the comfort zone by name itself means happiness, so why challenge and stress yourself and become uncomfortable? The only place I can agree is if this zone is inhibiting you to achieve what you wish to, like becoming a Head HR, go ahead and challenge as the goal is more important to you than the zone. But in general why keep moving out of the comfort zone. Please don't move my cheese, I like the predictability of it being here daily. I know the argument is that I will be less prepared to face challenge when environment changes, if it does I am ready to slog then. Adding stress and anxiety for fear of future and what may happen well I don't care. To those who believe in moving the zone time and again I will suggest be less fearful of future and the environment, it can change and go against you but at that time be ready to fight it, accept that reality. But for now don't be paranoid and just be happy and enjoy the comfort zone..

The only challenge which I like to take head on is my fears, as that's my goal to be fearless. This value is close to me as for a religious person is GOD. I am changing roles and I debated why am I moving out of my comfort zone, I am extremely happy with my role, the team I am working with. It is not the redundancy and growth as HR professional I am worried about then why? I have rationalized it now that it may help me practice new skills which I could not in the earlier years as I had a few fears, the fear is now gone and the new experience will give me to hone a few skills. Now I am looking forward to it......
