This is NOT how you win over a woman
Rather, wooing a woman involves a combination of these things, plus many more. Earning her respect is critical, and you do so by having or striving for a good job; treating your family, friends, and peers well; being hard-working and intelligent; and exuding honesty and integrity.
Being sweet and romantic should be part of the overall package, but it is hardly enough. All the flowers, chocolates, and cutesy notes in the world can never compensate for highly undesirable qualities like irrepressible anger, a slovenly appearance, and chronic dishonesty. Above all, if a woman doesn't feel she can trust a man, there's simply no hope for a relationship.
