It is not enough to buy something cheap and sell high.
No, I mean you can do that, and given you have enough persistence and salesman talent, you can earn loads of money.
What I want to say, though, is that we have lots of people out where without any special knowledge or skills, who want to get rich. They are getting involved into various “money-earning” schemes, from MLM to Forex Trading. Are they bringing good to the world, or just reaping the benefits without giving anything back? This is not a sustainable model.
The problem is, that many forget, that you can’t earn money just out of the thin air. You have to create (or add) value. Scientists are those who are doing it best. But between them and an average salesman lies a broad range of professions and specialties.
We better find ourselves among those. In a new world we are entering, competition is fierce, and opportunities are limitless. The only limit is your imagination. And guts, of course. Everything else is a commodity, which is to be outsourced.
