Sometimes the reason a problem defies our best attempts to solve it is because it's not the right time. Maybe circumstances aren't conducive, your idea is too ahead of the curve, or things have to get worse before they can get better. What makes the Venus/Uranus sextile on April 20th more successful than the previous sextiles on January 26th and April 8th is that both planets are out of retrograde. They'll be working together instead of at cross purposes. Moreover Venus, ruler of the sextile and in Pisces (sign of her exaltation) ensures you'll produce a solution that meets with smiles instead of furrowed brows.
