wind affects an aircraft only while the wheels are on the ground or you are navigating. a steady head wind doesn't increase lift, a tailwind doesn't decrease lift, a steady wind won't push you or cause you to stall in a turn. it will cause your ground speed to be different than your airspeed, your ground track to be different than your heading and your climb angle to vary depending on the direction of travel in relation to the wind. its not magic but it can be very counterintuitive.
