Check yourself and search urself in and out.
What are ur desires?
Where do u want to be in the very near future?
What do u see urself doing in few yrs to come?
What career did u plan for urself initially?
and which direction are you thinking right now after graduation?
I bet you if you can answer sincerely the above questions i posed you,
your decision will be as easy as you ever imagined.
If you have fallen in love with the Corporate world and its offerings, it will be difficult for you to go and lecture...............

If you desire more degrees and intend to educate yourself more in your chosen discipline, then you may be doing urself more good by taking up the Lecturing job.
It may amaze you, you can still go back to Corporate environment after few yrs if you so desire.
