Iho, sa mga posts mo, kulang ka sa confidence to make the first move. You rely on FB and assume/speculate on the negatives that you are still uncertain off. Akala ko ba nag-aaral ka ng law he he. Sa "Laws of Attraction" pa lang ay semplang ka na. Ang main target mo, makausap siya, di ba? Just go straight to her when you have the opportunity (personally), prepare yourself, time it correctly, say "hello" and introduce yourself. The rest of the conversation is up to you. Be genuine and be yourself. Yan yung basics, and take it one step at a time.
And lastly, leave something that she'll remember or think about. A simple touch will do. Kahit sa unang introduction, kamayan mo agad or a pat in the back after you leave. O patay-malisyang bulong sa tainga he he kung kaya mo. Bahala ka na. (Sorry at di ako gumamit ni minsan ng social media app to approach women. Not my style.)
Kung nahihiya ka for some reason, hand her a letter thru some proxy, then do the personal approach. Matatagalan ka kung mag-rely ka sa remote "friend request" he he.
Para ka lang naghuhuli ng mailap na isda sa dagat o mailap na hayop sa gubat. Learn to catch your prey! Walang imposible if you do it right.
