Reason number 1:
You will never achieve anything in life, think about that, think about life of mediocrity, this is the worst lifestyle of all, you know you can everyone knows that but you just cant achieve it. This is the case with 80% of the people on earth. And you know what they never do achieve anything, they just don't have that thing in them to drive them to success.
Reason number 2:
Your whole life you will be struggling to earn money and provide for your family, even though you maybe live ok and have a lot of things in life, still this is mediocrity and that wouldn't be the best that you can do. Would you like to buy your kids everything, to visit most beautiful places on earth, to travel, to have nice car and house? You would right? DON'T QUIT. If you didn't watch the movie "The pursuit of happiness" I highly recommend it, you will learn something about persistence.
Reason number 3:
Prove everyone that they wore wrong about you, for all the people that were telling you that you are small, stupid, lazy... Who wore undermining you, now the wheel of fortune is spinning and just picked your number. I was never big fan of gloating and you shouldn't do that, but some people just deserve to see how you are living and how are they living, doesn't matter if this is maybe your friends or teachers... Doesn't make any difference.
Reason number 4:
One life one chance - if not in this life then when exactly you are going to achieve all those great things? Never. You need to act and you need to act quick and smart, Remember this people who get rich doesn't work harder than you, they just work smarter. Be smart and most importantly be aggressive with your goals.
Reason number 5:
People believe and depend on you - don't disappoint them, they need that you be someone and achieve something for yourself and maybe them as well. You need to make everyone proud, but most importantly you need to be proud of yourself. This is the greatest feeling in the world.
Reason number 6:
Prove yourself that you are worth it. If you don't believe in yourself, who will? That was a question, ask yourself and think about that. I will tell you the answer, no one will believe in you and quite frankly most of the people don't care, but you should it's your life.
Reason number 7:
It supposed to be hard, nothing good comes easy and I like it. You should get use to this feeling. You need to glad that is hard, If it were easy than wouldn't be so special and no one would be even trying.
Reason number 8:
Be different, if you are like everyone else then you will be successful like everyone else. You need to be different than them. Be yourself and never care what anyone else is telling you. If they were so smart why aren't they successful...?
Reason number 9:
Never take criticism from people who never achieved anything, why would you in the first place? If they have nothing to show for them self, then they are not so smart after all they just like to be the first ones to tell you how this is not going to work out or you are doing it wrong or... They will find million reasons what you are doing wrong but for some reason they are not aware how little and meaningless they are by doing this.
Reason number 10:
You need a change in your life, or else you wouldn't even be trying. Doesn't matter what change the bottom line is you need it. So what are you still reading this go and start working on it.
I hope this post helped you a little to realize how life on this planet is short and there is not too much time left for wasting it on giving up and starting from the scratch your whole life, just start and DON'T GIVE UP.
