It is not wrong to believe what the system or someone else tells you. However I want to bear in mind that it is you to choose that path and by choosing to believe what a particular person or a complete system tells you, you will forever be a slave to that person or that system.
Everything is said to have a soul, nothing can exist without it. It is also said that the devil is after your soul. He is so because he does not have one but yet needs one to exist. Your soul cannot be taken but must be given.
If you believe what the outer world tells you instead of what your soul tells you, you will be giving away part of your soul for something that you only <em>thought</em> you wanted because the world out there told you so.
It is like a game and the only way to win is to choose for yourself instead of letting other people tell you who you are and what to do. Be the person you want to be, dream to be and do what you truly wish to do.
