You can start by becoming an agent in real estate. You will be selling houses for big developers. You will earn good commission and you will have good experience. You can also test there if you are up to the challenge of real estate business. You do not need to start with big capital. Just be in the business so you will know you are build for that business.
Getting a job like real estate businessing or any other jobs like that is not possible for everyone, because only the ones who have some relatives or friends in such business can get these jobs as they can be recommended by them, othewise it is hard to find a job like that easily.
A big no. I have colleagues who has no experience at all when doing real estate jobs and no such thing as known person associated with that kind of job but now living in lots of saved money.
In any job, if a person really wants it they will become succesfull no matter what. And because they are doing well in their chosen jobs, saving the money is just a piece of cake to them.
don't forget to invest your money too, if you have real job with highest salary and you thinking that's enough for live and saving, i suggest you to invest at bitcoin, or you can use bitcoin as sidejob and save the salary of your sidejob for invest in bitcoin.
