Limit?

What is one's limit?
Is there really such thing as limit in studies, feelings etc... ?

2 weeks into uni and i all i can say is life is quite hectic
lecture, tutorial, hall life, fencing, work
Maybe just maybe I am putting too much of things on my plate.

With what happen last night am sort of quite sure my tolerance level is quite low lately
Maybe it is the right time that i should give up

Not sure why i blog suddenly in the middle of preparing for tutorial
Perhaps maybe writing them out it can help clear my mind

Don't know what is wrong lately...
Friday was my last day of work and I have been thinking a lot
Uni matters, family matters, money matters.

I always say perserverance is the answer and the sky is my limit always. Don't understand why am losing my positive self so often lately. In fact too often that am afriad i might not be able to cope with everything that is going to come in my way when uni starts. Even have the impluse decision to work full time and withdraw from uni.

Is my life statements really working? Or am I lying to everyone so that others don't worry for me?
