What would be the best approach to ethical hacking via best source to start, what approach, what subject to work on first, etc?

I'm 28 and been always fascinated with software and computers in general. I tried to get into it before but I was overwhelmed and easily discouraged due to being depressed or other reasons. This new years I told myself, screw it I'm doing it an getting into it and sticking with it no excuses. I get easily discouraged but I don't want to and that's why Im asking what's the best place to start and go. Thank you for the support!
