there are not that many things we really need for healthy and happy life
Know the limits,
learn to limit yourself otherwise the Nature may limit you
every piece of bread you eat, every moment you live
to your parents, your teaches and all people who help you on your life path
Follow the rules
(traffic, ethic, corporate etc) and you achieve more and harm less
each individual is special with own Prakriti, own karma, own life mission. When you wish for some attribute of other’s you can easily miss your own.
