Always ?

I've always wondered : are tasks always ment to be done ? Should rules always be followed ? Or are those things just put out to guide you through the process of learning about Responsibility ? I have those questions in my mind , searching for an answer . I am put to do tasks very often , mostly tasks I do not enjoy ; but i once heard a saying that read : 'One should do what they enjoy' ; but I read another one that said : No one is where they intended to be' .I am a normal person , who enjoys things , and can't stand some other things . That's what has me wondering : Should I Persue my life long dream ? Or let other doors open while doing un-enjoyable tasks ?
