I work full time and trade for an hour or so before work, my peak trading time is between 9:30-10AM EST, then maybe a few plays up until 10:30 or so. If you can focus for the first half hour that is all that is needed at least for me to get my trades done. That's plenty of time to catch good moves. Similar to Andrew. But you do need a solid 15-20 min prep to run through the scanners before the market opens. It's gonna take at least a couple years of daily trading to improve accuracy, be patient, remember college, grad school, medical school, law school all days 4-5 years to complete.
