Welcome to the club no one ever asks to join. You're A1c is not too bad, so you've found out fairly early. They ought to give you a better chance to keep diabetes in check/under control. Just remember that Type 2 diabetes is a progressive condition, so it is possible that you could do "all the right things" and still find it gets more difficult with time. That's what happened with me -- should that happen, don't discount your efforts until then -- you will still be healthier and probably more fit for your efforts!
Meanwhile, I'll echo what @Terry4 and @Uff_Da said -- carbohydrates are what you have to watch, food-wise. It can be easier when you have less carbohydrates in your die - though you have to find what works best for you. Get a meter and use it to see how food, exercise, stress, meds - everything - affect you. Every PWD (person with diabetes) is different and reacts differently to things. I can eat food safely that send others' BG soaring, and things that make me go high might be just fine for you. You can only know what works for you by experimentation.
Be active here -- there are a lot of people with a lot of different experience here. Though, you will be different, asking questions and taking advantage of the experience of others will help chart your journey. As they say, diabetes is a marathon, not a sprint. You will have good days and bad -- you have to look at the long-term picture. Sometimes things will go wrong, true, but, as a good friend here once advised, when something goes wrong, think about it for 17 seconds - if you can figure it out, learn from it and correct whatever happened, otherwise, just move on and do what you have to do.
