Online Spanish courses is a good way to learn Spanish in your free time. I mean who really had time to learn an entire new language these days? Unless you have a reason to learn a new language then why do it? Whatever reason you have to learn Spanish or not learn Spanish knowing any words or phrases will help you. There might be a time when you meet some Spanish individual and you can impress them but speaking Spanish with them to an extent. If you travel to a Spanish speaking country you can ask directions in the cab in Spanish.
