Calling

This morning, I watch short ad about Oprah's talk show of Super Soul Sunday and they were talking about " calling".
It hit me right on, especially after last night, being asked by my friend about what's your plan for the next 5 years? One thing for sure, I do not have any plan of having something expensive like cars or bags like my friend suggested.
Here are things have been bothering me since;
We live with more than one callings; these callings sometimes can change as time flies by.
Some callings might end on some time. And we might have new callings down the way.
Some callings might be called away from us.
I was like....oookkkaaayyyy... now I am a bit confused.
