Paying for driving instructor courses

I don^t know about you but I hate this feeling when I don^t have the money that I really need. Sometimes even though you try to save some money (I do it, as I always like to have some back up if something goes wrong) you can^t pay for a certain product or service. This situation is really frustrating for me because I always think that I have done something wrong. I feel responsible for this fact and that is why I start working even harder than usual. That is my way of dealing with it but I imagine that it is not the best thing you can do. Recently in such situation when I needed money fast I had no choice but to borrow some from my friend. I needed to pay for driving instructor courses. I hate borrowing money as I am really stressed by such situation. I keep on thinking when I would be able to give this person his or her money back and it drives me crazy. I hate having debts. The problem with driving instructor courses was that even though I have finished them I still didn^t have enough money to pay my friend back. That is why I took extra job and it took me one month to collect the money needed. I am happy that I no longer have to worry about it and I got rid of this debt.
