Thats a huge must for generally surviving on an economic level, always depending on your life value. You can invest on something that will get affected from inflation and the price will go up, for example if you have bought gas forex or invested in real estate.
My suggestions is to start building a internet marketing skill on something and start making some extra money with a 9-5 job for the stuff like rent,gas,food. Try working remotely for local people in your area, like business owners and suggest them stuff to do for better exposure on google or any stuff like that.
