A good starting point in your quest to make a home budget, is to take stock of your current and recent situation, and list out all your monthly outgoings. If you only do this from memory, there is a chance you will miss one or more important items. You probably have several sources of information on what those regular outgoings are, and whether they are easy to find depends on how well organised you are with your paperwork. It is worth checking back over at least three months bank and credit card statements, and jot down what your regular payments are out of those. At the same time, you can also make a note of items of expenditure that may recur later on.
Build a solid foundation knowledge, you will find that all the programs upgrades is quite easy for you to understand. This is because the core foundation will not change. When it comes to learning new things, you want to take it one bite at a time. Don‘t punish yourself if you can‘t get it the first time. Don‘t give up easily. If you don‘t know how to even write an email, start by just register an account. If you don‘t have a computer, start by using the computers in the public library. Be flexible with the approach but be firm with the intention when it comes to learning the new technology.
