As an Asian man - If I was single and I "hit on" a woman on the street once a day, it's more likely than not I'll be in a relationship within the month. It's not that hard, I often wonder how easy it is for non-Asian men. Do you just turn on Tinder and find yourself sleeping with women within 24 hours?
You've got more bravery than most to just walk up to a lady during the day and say hi. That more than makes up for any disadvantages your race may put you at.
