If I Could See Tomorrow

Scratch that.
If I were psychic, (Oh Lord!) I'd be passing out winning lotto numbers like an Alajo to Kaneshie trotro mate giving out change.
My fantasy would be to hit the jackpot of every lottery organization in the world. Oh, and I will make it happen. That would keep me busy enough that I wouldn't have time to set up shop reading palms at street fairs
What's the deal with psychics? How come they supposedly have this talent to predict stuff but have no clue what's in their future?
