 - Instead, she could only remember events and experiences that were yet to happen.
 - At first, Jane was disoriented and confused, struggling to make sense of this new reality.
 - But as time went on, Jane started to embrace her unique ability and see it as a gift rather than a curse.
 - She soon realized that she had the power to shape her own future and make choices that would lead to positive outcomes.
 - Jane started journaling about her future memories, using them as a guide to navigate her life.

 - However, Jane also faced challenges as her ability to remember only the future sometimes made it difficult to connect with others on a deeper level.
