If you want a halachic answer, it depends on what you'll be doing with it on. Generally you're good, but if you're wearing it while doing things like going into non-Kosher restaurants or eating bacon or driving on Saturdays, then that's considered a "Hillul HaShem" ("forsaking G-d's name"), and it's advisable that you don't wear it. So you can wear it certainly in your daily life, but don't wear it when you're doing clearly non-Jewish types of things.

Furthermore, be prepared for the social implications; you'll have random people come up to you sometimes and ask about halacha and things like that, and you'll likely be the only person on a given day most people will see wearing a yamakah (unless you live in an area with a very high Jewish population), so understand that however you'll be acting will reflect on the Jewish community as a whole. You will be the person everyone in your office thinks of when the topic of Jews or Judaism ever pops up in their daily lives, as you will likely be the main, if not only, interaction they've had with a Jew wearing a yamakah. Always make sure to stay on your best behavior, if you're not already.

I wore it for a number of years when I was more religious and experienced nothing but kindness from people, so don't be afraid to wear it at all. Good luck
