Almost 30, now engaged in elevator installation. Is it a bit unreliable and hopeless?

Now that you are 30 years old, you should have your own opinions. You can ask yourself why you want to install the elevator. In fact, as long as you want to do it and work hard, there is no saying that it is unreliable or has no future. Besides, you said you didn't know whether the installation of the elevator recruitment network was true. I work in elevator maintenance, and my job was found on it. Workers are also looking for a job on the elevator recruitment network, which can help you find a job, without lying to you.
