a new horizon

Sometimes I really feels like I’m on automatic pilot  ,  going thru the the same old routine  ~  waking up , going to work , spending 8 hours in front of a desk , then going back home to sleep and repeating the whole cycle again the next day !!! 
Don't get me wrong  ,  I'm not complaining , in fact , I'm grateful that I'm still able to wake up , having the ability to make my living and I do get some enjoyment along the way , in the form of frds , family , loved ones , and interesting happenings . Yet I still feel like there’s something missing . This unsettling feeling keep on nagging me . Sometimes , I feel like I’m merely existing !!!! 
In fact  ,  I've handed in my resignation countless of time in the past 3 years , but my clients , my boss and my co-workers keep on persuade me to stay ( especially F , my wonderful boss ) . But day in day out , I feel like I can’t take the monotony anymore . It's about time to leave and explore new things .
