Hi there Ron.
Welcome on board.
For the workplace, IG + IS makeas a good mix, somehow subtle, but powerful. At your age, A314 seems too much to me, but you may want to give it a try.
Once you have been using this mix for a while, and if you are getting good feedback from people around you, you can try adding some AMMO and see what happens. Start with just one spray and see if you can notice any difference.
Ideally, you should start using every product by itself, at different doeses, starting by one spray, and building your way up, as explained in SteveO´s clasic post: How to find your sweet spot...
Also, you may find some useful info on this thread: What works: BUSINESS APPLICATIONS (sales, meetings, etc)
As for the process, a regular shower should be enough. Be carefull to rub all the mones aplication points with soap and hot water.
For being more approachable, i would suggest you to use some IS and IO, and don´t forget to smile back, initiate eye contact and keeping it when initiated by someone else. Mones can help you, but you still have to do most of the job.
Hope this helps.
Talk to you soon.
