Whatever you do start your own side business. That is the most important advice in life. If you have a side business even you loose your job you can still make money and develop your business into a full-time job. If you work a full-time job then it gives ou extra income and safety.
There is nothing more important than having a side business!
If you work full time, then you have your own extra business very hard. Therefore, you need to look for a passive source of income. But the problem is that you need to have an initial capital for this
The initial capital is not a problem, but if it's your last money you do not want them to risk it. I think that the person before you invest money in a project must be an expert in this field and the risk of investment should be minimal. Become an expert in another area if you have full employment very difficult.
Yeah money is not a problem to have a capital but you must have a skill, dedication , work smart , work hard, and also motivation for you to have a profit. Discipline also needed if you will join in some signature campaign.
