Shifting into gear while moving???

So for example if you are on the highway going 60 mph and you take an off ramp with a sharp turn at the end and you say "OK, I will need to be in 2nd for that turn, so I will just push the clutch in now and shift to 2nd at 60 mph" you are going to feel significant resustance and doing this often will cause a lot of wear on your synchros.
