As George says, try and achieve a sweeping curve. The movement of the gouge through that curve can be eased by an upward sweep of the flute from the start of the cut.
Easier said than explained, but I'll try.
You touch the tip of the tool onto the wood to create a start for your bevel to rub against, you turn the tool so that the flute starts to cut and ease the tool into the wood. At some point not too far into the cut, it will be easier to push down on the handle, bringing the cut upwards slightly, you will need to keep the angle of the flute adjusted at the same time.
Just over the half-way point through the shape of the bowl curve, the tool will cut easier if its guided back down by lifting the handle.
You should finish on the centreline cutting through the center and hence not leaving the little pip.
The curve followed by the tool is sort of a 3D Sine Wave. If you've never cut like that before, don't try it on the final cut, practice it on preceding cuts remembering that you are practicing each cut so that you can make the final cut with confidence.
