Traditionally, people would have to choose according to gender or birthday.

• I can't relate with either the Magician or the High Priestess. Blegh, Paul Foster Case's rigid gender binary.
• King/Queen of Swords, or Justice, if I go with my astrological signs.
• Hierophant if I go with numerology.

Here I'm listing down cards I think stand for me during various situations I'd read tarot.

• Page of Swords
• Knight of Cups
• 9 of Wands
• 2 of Swords
• 8 of Pentacles
• 2 of Wands
• 8 of Cups

My reservation with using significators would be that I miss seeing how else it could figure in a spread if I left its (non)appearance to chance.
