Grow gratefulness
Being grateful means that you are thankful for all the blessings God has given you. Do not always look up, look down, look at people less fortunate than you. Do not get stuck in the past, and do not think too much about the future. Just do your best today, because tomorrow we will never know what will happen next. So relax and enjoy your life. Do not be too upset and not too ambitious (greedy).
