Is it possible to study electronics after 30?

Question

Electronics

Question for those who have been involved in electronics for a long time.
Is it worth it to take on this business if you are 32, and the goal is, say, to make synthesizers, or simple household gadgets? And how long can it take to achieve the goal with intensive self-study (6 hours a day, say)?
There is a mathematical background, there will be no problems with formulas. I also picked up the literature, but, having started to study, I understand that you have to think about some topics for a long time and hang on the 1st page of the theoretical material, it happens that almost all day.

Answer 1

How does 30 differ from 20 in terms of learning? If you see potential in this and you are INTERESTED, then everything is real. As for "how long it will take": no one will ever tell you that. A person's ability to learn depends little on literature or the number of hours. You can solve a bunch of problems in 6 hours, or you can sit over a trifle for 6 hours. You can subtract smart things from a weak book, or you can read an ideal training manual and skip half.

Answer 2

It's unrealistic, forget it)
Most likely, it's a matter of determination and need.
