Mostly life will be perfectly normal.
At .38g normal day-to-day activities would proceed normally.
It is enough gravity to not bother sleeping (it should be more comfortable!), standing, sitting at a desk, eating.
Your paperwork will behave and sit on your desk, your food likewise.
Liquids in open containers will be a bit more unruly (2.5x wave height for same disturbance), but that simply means don't fill your glass of juice to the brim.
Walking at a normal pace should be similar, although you will have a bit of a tendency to bounce more than wanted. Also, due to having the same mass but only 38% the weight, traction will be less than expected. Walking would be something like walking on a linoleum floor with socks on. A bit slippery, but nothing unmanageable. And ignorable if you wear the right shoes.
However, once you start getting energetic, the lower gravity will be bothersome.
On Earth, a vigorous standing jump might lift your feet 1 meter.
On Mars, that same jump(same starting velocity), will take your feet up to 2.63m
Which is a problem, unless you make your ceiling 4.7m above the floor!!
Also, traction for running will be a big problem, unless you prepare for it with suitably grippy shoes, at all times. Even then, expect people to tip over running around a corner much more, and use their hands to stabilize when turning or stopping in a hurry.
With everything having the same mass, but only .38 gravity, you will be able to lift quite a bit more. Pure "lifting strength" will appear to be more than twice as great.
Unfortunately, .38g is not quite low enough to make human-wing flying possible. Sorry.
Stairs will be interesting.
The lower gravity makes going up stairs very easy, and they could be quite steep indeed.
But, the reduced gravity will make going down the same steep stairs very problematic.
We already experience a bit of this on Earth, where it is immensely easier to trip going down steep stairs than up. Reduced gravity will make the pain of falling less, but the likelyhood much greater.
Possible alternatives: (speculation, really)
Moderately steep rampways, instead of the terraced stairways we are used to?
Possibly with the "down" lane being just a slidespace?
Or the extreme version of this: Up stairway is a ladder, you ascend on arm power.
Down stairway is an oldfashioned fireman's pole, possibly with a friction-controlled hand strap?
Due to the lower gravity, your muscles and cardiovascular system will not get the routine exercise it needs. The problem is not nearly as bad as on a zero-g station, but you will still need to adhere to a strict exercise regiment to maintain good health.
There should not be any real long-term debilitating problems, but frankly at this time we just do not know, it is one of the things that can only truly be tested by doing, not studying the problem.
