Some of us have been learning electronics for quite some time - in my case about 55 years.
I know quite a lot of stuff, and I know enough to know that there is more that I don't know than there is that I do.
Like all skills, electronics requires a little aptitude and at least 10000 hours of practice, to reach a level of reasonable competence. (because that's what the other guys have put in and some are always going to be smarter than you.)
I estimate I've put in over 100k hours of effort in electronics - there are no short cuts - so we are talking about where you might start.
If you need just one pointer, then try "The Art of Electronics by Paul Horowitz and Winfield Hill" (Third edition ISBN 978-0-521-80926-9).
Chances are you won't understand a lot of it so you'll need to read around it as well.
Be very careful about sites like EEWeb and All About Circuits - both are popular and crammed full of errors and misconceptions.
There is good stuff on the web, but more poor stuff - and it can be hard to tell the difference.
you can help me with someone who will always guide me please
