Anybody with ADHD highflying/ smashing life . What's your secret?

So I haven't been diagnosed as having ADHD but my son is currently going through the diagnosis stages. This has lead me to believe that I too have this. I consider myself to be doing alright/holding it together but I find myself constantly looking of ways to self improve and be a better person/Dad / husband. So if you are smashing life how do you manage it and do you have any tips for the rest of us.
