Life is our enthusiasm to do things, and everyone who loses his enthusiasm won't be able to great things, every nation has its own energies, abilities and enthusiasm, great people in these nations have great energies that allow them to be enthusiastic because losers are not like that, they don't want to explore their abilities and use them to change this world, this enthusiasm is the limit between disability and creativity.
You can challenge everything in this world, you can make your today completely different from your yesterday by thinking about how to better yourself. When you try to make an improvement, everything comes easy to you like the universe wants you to be better, disappointment won't change anything because when you're disappointed you are useless and no one gives a shit about you or about what you are suffering for, it's time to get up and be what you want because the world isn't your mom : when you cry all day and close on yourself in your room she will come to you at the end of the day giving you something to eat, the world isn't like that it will let you die starving and no one cares.
Great ! now you know what to do but you may ask where to start if your life is full of disappointments, let me tell you that most beautiful things were created in the hardest of times, let me tell you that the diamond was a carbon at the beginning. If you feel like a loser, then how do you realize that you are a loser ? try to do something and believe me it will be great in the end, inside your dark circle create the way to success, search for improvements that will guide you to the light and believe me this is the biggest challenge you will ever see because if you figure out that, then everything will be easy.
Every great story that you read about great people is created inside their dark circles, that's why they are great, their abilities and experiences are stemming from the hardest conditions they have ever lived. People in this world need more smiles, they need light, they need someone who is able to break all the rules to be better.
I won't make it philosophic for you.
Thank you ;)
