Avoid all unnecessary expenses and just learn to live within your comfort. You dont have to pretend that you are always able to buy this or that just because your friends have been telling you. Where in fact your finances are already struggling deep inside. So just live within your limits and you will never have to face financial problems later on. When you have that mindset, your finances will never be compromised and wont never fall into unwanted debt.
We have to adapt our lifestyle to the economic limitations that we have without being affected by the lifestyle of other people, so we have to manage expenses according to the limits of funds for shopping needs every day without being related to debt. But another solution, I quoted the post above that we must prepare our savings for emergency fund needs, because in conditions of economic stress it is very difficult to apply for a loan from a bank or anyone unless we have assets to pawn.
