If you are really aggressive, you only need to keep money in your checking account between your payday and the due dates of your rent, utility etc. Everything else can be invested instantly on your payday. If that amount of money is significant to you and you think you are missing out, you should stay away from the stock market. You are basically on the verge of bankruptcy, especially if you live in a country without proper social security (e.g. the US). I like the idea if you are saving for something you do not really need, e.g. your second yearly vacation or some vehicle.
