If you have any experience keeping reptiles and especially other turtles or tortoises, I don't think a russian tortoise will prove to be difficult for you.
But just in case:
1) You cannot keep a russian tortoise (or any other full-sized tortoise) in a small enclosure like a 10 gallon take. It must have plenty of room to roam around with things to crawl over and hide under. It likes to dig. This makes an indoor enclosure more difficult to design. Except for brief periods, a russian tortoise should have at least 8 square feet of floor space. If you go smaller (say 6 sq ft) then you need to put a lot of effort into the layout. Such as creating multiple levels for the tortoise to explore. If you create an outdoor pen, be sure to sink the edges of the pen 6-12" into the soil. I have hard clay soil in my yard, so I only sink the boards in 6"; softer soil requires deeper boards. Also, with an outdoor pen create a larger area. My outdoor pen is 64 sq ft for 4 adults.
2) Feeding: while there are canned foods that can be used some of the time (some people use Mazuri, I sometimes use Pretty Pets tortoise pellets), most everyone uses a mix of grocery greens and weeds, clover, grasses collected from a chemical-free area. See the website listed above for suggested foods.
Summary: Give it room (no little fish tanks or small tubs), give it heat and hydration (see website), and good natural foods (and a little canned stuff if you need to.)
If you can deal with all of that, then a russian is a good pet for you. Also, they don't really need to be hibernated, but if you can do it properly it doesn't hurt.
