Transition to it from another sphere?

Question

IT education

HI ALL!
There is a question that now torments me very much, I have worked for many years already in sales. Now I work in a decent position with a salary of 120+. But the soul does not lie, and in general I think for a couple more years, and in general my entire sphere will be digitized, and I will have to run. For several years I have been dreaming of moving to It, I didn’t go beyond videos on YouTube. And now I decided to take annual courses in "NETOLOGIA" as a system administrator. I understand that development at my age will no longer "go". Yes, I am 31 years old. Do you think this is not a completely stupid step? Is it realistic to break into a profession from scratch? In principle, in theory, since everything is digitized, perhaps the knowledge will be useful in my field, if it doesn’t work ....

Answer 2

In fact, the age for changing a profession is not a problem, especially in IT. Yes, there are prejudices, but there are many examples when people change their profession. And of course, you need to understand that for every successful story there are 10-13 people who did not succeed for one reason or another.
To answer your question - no, not a stupid move. Think carefully about why you need to change profession, whether you are ready to work with risks, for example, is there an airbag, time for training. Regarding the latter, you need to understand that the learning process does not end with one course. Therefore, if you think that courses will make you a specialist, you are mistaken. You need to be ready to study a lot of new information, read books, communicate with professionals in the field.
