How do I use italki to learn italian more effectively ?

Now I work in the textile industry in Turkey. I think as somebody in world as if we always have to improve ourself. Otherwise we feel always behind in the race. It is not a perfect attitude, I know. I never advise* my children to have such a habit. Reading good books, having good friends, travelling abroad, and having wishes to know other cultures are better lifestyles. Although I know what is better in life, after an age it is nearly impossible to change something in our head. It is like the different ways of going somewhere. In a city many routes were made like they are because people have used these ways for many years. I mean these ways are there not because of the result of an engineering work. Sorry for extending too much, I want to learn italian. I had a few months course here by an Italian cours[??]. I stopped it because of my job. Now I want to start again and found this appliacation. Please could you kindly explain how I can use italki more effectively to learn Italian. I wish my best, see you.
