life and challenges

are we able to withstand the swift water? maybe this is a silly question, but we need to know that life is full of challenges. don't waste it to move better if we don't follow our hearts, others cannot understand the contents of our hearts. maybe it takes time to understand life. because we only run it all this time. in what aspects do we see this life! is it just chasing a dream? Does the pursuit of material never run out? we live this life must be fair, because we are not always satisfied with the material. indeed we often feel happy and sad. Because, happy and sad are special guests for humans. Whether you want it or not and don't accept it, it comes unexpectedly. And depending on us, we must welcome it with selfishness or tranquility.
