The Page of Wands shows us a young person, dressed in yellow. The yellow signifies creativity, being positive, or even hopeful. He also holds a budding staff in his hands - this is a person who can make things happen when he sets his hands to something. The buds are also a symbol of growth. The mountains in the background are the challenges of yesterday. The desert is a symbol of discovery, being alone, or reflection of the past. The reptiles on the persons outfit represent change, growth, rebirth.
So today certainly is a day of change, learning from the past and taking those lessons to heart and becoming better - better at work at your job or perhaps learning how to handle difficult situations or relationships. Yesterday is yesterday, reflect but do not dwell on mistakes - take them to heart, see where changes can be made, and move forward to claim the rewards of the future.
