Like Martina said herself, she was playing in fear. Now she can't be afraid of losing the #1 ranking anymore. She's really going out there, fearless.
And soon she'll make her way back to the top, where she belongs, no doubt about it.
And when she's at #1, she'll be confident enough, this time, to know that she CAN beat the power players, and she'll remain fearless, and keep that #1.
