Yeah, 5'3 is kind of short but everybody has a handicap. I have tinnitus and really sensitive ears so I have to coach my dates and gfs re: how "loud" something can be or I just pop in earplugs--but I need to take them everywhere. Concerts and live bands are out though. I don't dwell on it and have a good time--and no one has ever cared one sh*t.
A friend of mine in college was maybe 5'5 and he did OK--he mainly dated shorter chicks. Here's my 3 step plan for you:
1- Develop HUGE confidence. Listen to some Tony Robbins Cds and buy some books, practice makes perfect. Many studies say it's the number one thing girls look for.
2- Develop an AWESOME sense of humor. Women LOVE funny dudes; many studies say this is the number one thing they look for--so now you have #1 and #2 covered.
3- Just do it. Ask out all kinds of girls. Be Brett Favre. Most guys are so f-ing petrified of asking a hot babe out, you would have a huge advantage. Keep in mind, 90% of all guys are NOT DJs, 80% of all guys are probably taller than you, so by practicing stuff on this site you just leveled the playing field.
You may even have an advantage over some guys because chicks will not view you as a threat or player. You can probably befriend them quicker and then use DJ skills to score with them.
Thanks to Mother Nature, working out hard, and just keeping up with things, I've kept good looks into my 40's. I have better luck now with chicks in their 20's that I did when I was in my 20's. BUT, I have on more than a few occasions, had chicks make me wait for sex or they play really hard to get because I "look" like a player (I'm not complaining but it's happened). Some have told me after the fact and admitted that they’re like "OK, this guy is good looking, muscular, owns his own biz, etc.--he MUST be A-Grade Player. If I date him, I'm going to make him WAIT big-time to make sure he's really into me." It may be happening to me right now with the current babe I'm with!!
Work on yourself and you'll have NO PROBLEM, my man!
