I think 30 years old is already a watershed , if you do not have anything to do, and do not have skills, you can try to start from the grass-roots level, as long as hardworking and hard work to be appreciated by the boss, you can earn money.

The easiest thing to do is to go to a construction site. Site does not need education, do not need to say you have much ability, but you go there from the grass-roots level, 30-year-old male physical strength is also okay, as long as you're diligent enough, it is possible to be appreciated by the contractor, he will give you to take over some of the small work and so on, and then there will be a commission and shares to the back of the more and more efforts, or may become a contractor and so on.

Can be delivered to the courier, now the courier industry is very developed, but also very need people. In the beginning, you can go to the first dry courier, later, for example, you can go to the school to contract some courier station or to run their own courier, slowly are getting better and better, the profit is also still available.

Can go to learn a craft, now really rely on the craft to fight the world, for example, can go to learn to cook as a chef,After all, now the catering industry service industry is also very developed. Nowadays, chefs are really well-paid industry, in the street are most of the restaurants, 30 years old is not to say that very old age, it is perfectly possible to try to learn a new craft.

Or you can go for a teaching license, it's a more stable career now, and there's no limit to your age to go for a teaching license. I've known a school driver who went on to get a teaching certificate and then opened his own training center. I don't think it's too late to try to do all sorts of attempts at 30.

I think now which industry is a chance to earn money, as long as you are capable enough, hardworking enough, are able to earn money. 30 years old say young is not young, but say old is not old, mainly to have self-confidence in themselves, dare to start from scratch is good.
