i will do my best to keep up to date and get better at online security, but as i get older i find it harder and harder to keep up.
Could help you on this:
Personal Security Checklist (note: treat it as a guide, you don't need to do everything and double check first)
It gets easier once it becomes a habit (kinda like muscle memory.) You could also use what happened today as a motivation whenever you hit a roadblock.
