car runs kinda crappy when cold

this is normal right? like after i park the car for the night, and go out in the morning and start it...i usually let it warm up a bit then drive it...and it's a little difficult to shift from gear to gear...also the clutch engages a bit rough but this all goes away after about 15min of driving the car...my dad told me this is perfectly normal but i just want some reassurance. thanks for the help.

Its normal, I believe the shifting is in the owners manual and there it says its normal.

it's totally normal. the piston moving inside the cylinder works the best and most frictionless when the motor oil reach a certain temperature. so before that, you'll notice some loss of power.
