What am I busy for?

Exams..studies..assignments..ministry..week in week out..phew "=.= it's overloaded!! ..cause me to ponder what am I busy for??..
I received a "refreshing call" that day from someone in the midst of my business..it came at a right time that really encouraged me..I just have to get away from my loads and come back to the place of just being me and God..little do we realise that business and tiredness can grab away the space we have with God...sometimes i just need to remind myself what am i busy for??..is God getting involved in things that i do??
