Work or Career?

I will graduate shortly (around the corner,) and, although it should be a happy event, sadly it is not the case. (thing to me, but it`s not.)  The reason being that (Because) I don`t know what (is the favorite thing that I want) to do for a living. (my whole life.) Nevertheless, (However,) I do need to work, (for livehood.) so (I) have been contacting (starting interview) many companies with a view to attending interviews. (when I don`t know what I want to do.)

My ambition is to forge (I desire to have) a great career, not just get by with a boring job. (work.)
Whatever, I will give a lot of thought (work hard) to determine (find out) what I most want (mostly love) to do.

Hello Mavis. I have suggested a few alternative phrases you could use. We do not usually start a sentence with a conjunction - such as 'and' or 'because' (as per your second sentence).
