One does not need to give up one's identity and roots to adapt to a new culture or country. What is needed is to embrace the new with all that is in you and not without it as then in the true sense will that will mark a true journey in your life . A journey of growth begins not with over adapting but with adapting and yet retaining what you already have.
You don't have to give up yourself or lose yourself to embrace the new. You can accept the new environment with an open mind and yet treasure the old. Finding something new in your life does not mean giving up the old. Embrace the new but also retain the old !
