Can I successfully trade with only 2-3 hours per day?

I have a job, and I would be able to do a MAX of 2-3 hours of trading per day. Can someone tell me the basics, how long would it took to learn it, where is the best platform to learn it... These might be annoying questions, but I just want the truth. Can I do this with 2-3 hours per day or not. Thank you.
