An asset is anything that can make you money. If you happen to have access to some land, you can grow a crop on the land, harvest the crop, sell the produce, and you then have money even though you did not need to own the property to use it. That is just an example. I do not suggest share cropping since that doesn't make the most money or even a lot, and it takes the investment of your time and effort.
A liability is anything that costs you money and doesn't return enough to ever pay for itself. A house that you live in is almost always a liability. Having a nicer house just means you will pay more in taxes. But of course it is necessary to live somewhere that you can get proper rest and clean yourself each day. The important thing to know is that you should never consider ones own house to be a good investment. Housing which you will rent out to other people can be an excellent asset. Of course there are risks, the investment is usually high, and there will be a time of years before your investment is paid back. If you already have a house and it happens to have a spare room, then you can rent a room out.
It is the attention to small things that will make you big money.
The fastest way to make the biggest profit with the least investment is to be the middle man in a deal. You find a buyer and a seller and without putting down any money of your own, you make the transaction. You accept a check from the buyer, deposit it into your account, then write a check to the seller and you have the product delivered directly to the buyer. The larger the order, the more money you can make. You only need to increase the price in order to make the profit. You may need to pay taxes as both a buyer and as a seller in most countries, so another way to do it would be to charge a "finders fee" or a sales commission rather than act as an intermediary merchant. The laws vary depending on whether you are selling manufactured goods or real estate etc. The larger the transaction, the more you will make for your time, so the goal is to sell to large organizations, corporations, etc. which tend to have needs in bulk.
Another way, which borders on the unethical but is legal, is to get people to work for you for free. You can do this in a number of ways. You can entice them with the idea that they could earn big commissions. Say they could earn as much as $1000 per week if they work hard. Then put them to work on the phones making cold calls to find the buyers which will then be matched to the sellers. Of course they only get paid a commission if a sale goes through, so they might earn nothing. Make sure they use their own phone and work from home so that it costs you nothing.
If you can get 1000 people to pay $10 per month for a product such as term life insurance or an extended warranty for computer repair service, that's an income of $10,000 per month. With that kind of income, you qualify for a mortgage to buy real estate which you then would rent out, charging enough to pay for the mortgage. So to get started you just need to leverage some free labor with the elusive promise of big commissions to make calls for you to sell something to collect payments now which you will provide the service later. Of course, managing a pool of callers, obtaining loans, developing a product or service to sell, managing the real estate you buy, etc. all takes a lot of effort and investment of your time. And there are things that can go wrong or risks. But if you research all the applicable laws and invest in your knowledge then you can mitigate any risks. Then after your experience, you can write a book on how you did it and sell the book to lazy people who dream of doing it, but who will not invest their own effort to actually do it.
To calm anger when you are on the phone takes practice. The first step is to recognize that you are angry and you don't want to be. The second step is to calm yourself down. Often just the realization that you are angry and don't want to be will take your mind off the subject of your anger and allow you to calm down. Realize that most anger over the phone comes from unmet expectations. Also, frustration from feeling helpless often causes anger. If you need time to calm down, sometimes it is best to hang up the phone. You can suggest that the phone was disconnected when you call back if you feel you need an excuse. The more often you are faced with anger in which you successfully calm down, the easier it will become to calm down. It is a skill that is developed with practice.
