If I were to move out of Metro Manila, I would most probably opt to move to the provinces instead of abroad. The cost of living is lower. The pace of life is calmer. Depending on which province (I was actually thinking of Davao), I could probably still teach.
Speaking purely for myself and without any prejudice towards those who opt to leave the country altogether, I find a great deal of meaning in the work that I do. I do not just refer to the college teaching. I refer to my extension work as well, especially the training and consultancy work for the public schools. The context in which I work is important to me and I don't think I could be as satisfied in another context.
So, I guess this is my way of saying I'm not going anywhere anytime soon. Or if I leave at all, it will be temporary. To paraphase the Arnold: I'll always be back.
