I have told dozens of students over the years If you're not happy with Aikido go get a Shodan in something else THEN give Aikido a go...Your perspective may change a bit.
Good Luck. Some of your post (as Don Hinted at) does not make sense but hey what do you know? No disrespect but you're just a beginner.
Again Good Luck.
P.S. If you're working as a bouncer at a bar Then Aikido actually works GREAT...At least that is my experiance. Restraint, Diplomacy and Martial Awareness are the tools of a good bouncer. Having a Good Left Hook is cool too but destroying unrulely drunks usually leads to to you getting destroyed in return either by his friends or the legal system.
