As you read in part one (if you have not read part one I suggest checking it out before reading this, although you will not miss out if you do not) you'll have completed your Microsoft training that a whole new world of career opportunities are now open to you, and you should not be afraid to move on from your current employer if you feel you are undervalued, in this section I'm going to focus on the emotional benefits of getting your Microsoft training. So let's assume that you've left your job, you're going to be without a source of income for at least a little while, but do not let that worry you.
Microsoft certification is one of the most respected and acknowledged qualifications in the industry so you should have little trouble finding work afterwards but do not take the first offer that comes on the table, this is your livelihood after all and you do not want to put all that effort to waste by accepting the first thing that comes your way.
Whilst you're in a lot better position to climb the career ladder than before you must not be afraid to start somewhere near the bottom, if you're confident in your abilities (and you should be) then you'll find yourself getting regular promotions and on your way to a bright new future in IT.
As I have said before, all of this is purely opinion and following anyone's words but your own is never a good idea, but hopefully I have given you the reassurance in order to go ahead and take chances with your life. Good luck!
