There is a saying, 'any port in a storm'. Think about it. Isn't that true? Think of your business in that way - and make the 'big picture' be that you survive by doing something, maybe lots of little things along the way. You do what you need to do to get by until you find your 'niche(s)'.
Remember you just need to get by when your home business is in development and you are living your dream to do something more than you have been doing so far or maybe just started lately. Many people have jobs that are barely tolerable because they feel that they have no other choice. Often they really are not happy, particularly in the current economic condition of the 'middle class' or 'working stiffs'-- the vast majority of people.
Big picture is You will build it up and make it something that you want and even better that you can have. In the meantime you will be planning and learning and changing as you GROW along. Most will also be working 'day jobs' unless they have some substantial savings to carry them in their new business' infancy.
So many give up way too soon because they don't realize what is involved and may expect instant results and/or to succeed without much effort. Maybe it is because of this that they don't really plan wisely and therefore never progress even to the basics of building a foundation for their business. They find an excuse to fail. No time, no money they say, when actually what it is more than anything else is a lack of interest in working.
So for awhile we have to work harder so that we can eventually then work smarter, which would likely be doing more while working less and of course making more money at the same time. Naturally MONEY is an element that concerns everyone, and particularly one who is trying to start a business. It is just not like a job where you get paid for your time necessarily at first - or as with a job, where you are usually paid even while learning!
But you want more than just working at a job! It really would help if someone enjoyed working and thought of it like any other decent art form, hobby or avocation. It is a "MEANS to an end", and a 'necessary evil'. It counts that we want to enjoy what we are doing even while we try to survive - because if we are working for ourselves it is a lot more natural or easy.
While we want what we want we are not willing to pay a huge price with our lives. Working takes up so much of everyone's time. Might as well like it! Or at least not let the stress cut our lives short! There are many sacrifices to have your own business unless you are in the minority of people who have 'extra' money to use for their business. (Yet some of the former don't hesitate to go on expensive vacations, and have wonderful entertainment) - nothing wrong with that , but maybe we have to sacrifice something if starting our own home business to make it our first priority.
