Atomics Physics tell us that atoms are surrounded by electrons, electrons possess energy and they jumping in and out, conducting electricity, forming bonding between another atoms and forming ions etc.
Well this is also true for human being. We have energies around us. I would like to category them into merely positive and negative energy. These energies influencing people around. Well...most of the time, people around you conducting negative energy like : oh thats difficult, oh shit, oh what the world is so unfair, you can never make it, thats sucks, forget it and give up and so on. Your friends might giving you a negative thinking and make our day down without noticing it.
Well, we should have positive energy around us. Things like we persevere, motivate, aspire and inspire are very important. You probably just wanna give a sigh on how bad your day is but this conduct some portion to other people around you.
Hence, you should keep positive, believe there is hope and the world is not as bad as you think. Change and empower will make up your day and light ups people's life and eventually they will shine you in other way some other time.
