As long as you're fine with lighting that money on fire, then sure, learn the ropes. You may have cold water running through your veins and trading might be your calling, you'll just never know if you don't try. If you're tight on money, but still want to learn, paper trade a bit, read a lot of articles (books tend to be outdated or try to cover too wide an area of trading).
If you like it, trade insignificant amounts, maybe a couple hundred dollars, but completely disposable income. Forget about being rich, forget about making a living, just worry about making good decisions, and worry about maximizing returns, and minimizing losses. There WILL be losses. Minimizing a loss that could have been worse is almost a win. My first GOOG trade in this thread I took my $700 loss and moved on. Had I held throughout the next day and "hoped" to make it back, I would have lost the rest, but instead I came back and made $500 on the next trade. That's how it is, don't let the losses demoralize you, it happens.
After you burn through the first few hundred, and you will lose it all, there are no exceptions, then ask yourself how you feel. Do you feel like you gambled and lost, or do you feel like you're paying for an education and you're learning/getting better, and still want to learn more? If you do, then keep it up, stay home and read/study while people are out eating shit and getting wasted and blowing their paycheck throughout the weekend.
