One of the things I used my time as a single person to do, was to get to know myself. The best way to represent my true self to others is to really know who I am.
This is a process and for me, was gradual. But, I did a spiritual gifts class at church, did personality tests (for the record, I'm an ISTJ) and did an extensive personality test via the site where David and I met.
All of these things, plus just a learning and listening to myself helped me to get to know who I was so that I could be an accurate representation of who I was and am.
