An ever typical long life lesson learned

I don't know how i got to this place. I always thought that my debut as a blogger would be more...sparkly or at least more organized and to be honest, it would have been.
 You see i had everything figured out. When the first blog would be posted what the subject would be even  the title i was going to use but then ; i got cold feet.
 I started saying to myself that it's not worth taking the risk and opening up yourself when you can't know the outcome and this is how the weeks passed and i forgot all about blogging  until i got bored and sad [I don't know exactly which one contributed the most on me being here and writing but i will go with the fact that i was bored] .
And so this is how i got here, siting in the middle of the night thinking about the meaning of friends and life and success on a business level.
You see until now i thought that the only thing a person needs to feel good is success on one sector of his life and after he had that, he could start thinking about everything else. Unfortunately the last couple of hours have managed to prove me wrong.
Now how did i come to this conclusion ?
It all started when today for the first time in my life  i managed to have full success on the friends level of life. Once i did that  i thought that i would feel happy and all my problems and pains would just go away but they  didn't. Despite the fact that i had all my friends close by and we were talking and being honest to each other i still didn't feel happy.To be precise a part of me did feel happy but another part was anxious and on the edge thinking about the coming exams period and about everything i said to myself that i will do but i didn't
That moment it started to make sense.
We are not complex only at a biological level but at a psychological one too. In order to feel "complete" we need more than to be safe or to have food, we also need to fill successful in life and this will not happen by focusing only on one thing and forgetting about all the others.
So to end, to all of you who are still reading this , i just want to say that being stuck up to one goal and sacrificing every other part of life in order to achieve it isn't worth it, cause when you do there is a big chance you won't feel as happy and complete as you thought you would.
