May I just offer my story? Maybe somewhere in it, you'll get an idea of some of the elements of time and circumstances...
I got the venerated (not) Rickeybird in 1984. I was in college and spent much of the day with him! He was my study companion and darling. But after about four years... it was time to go to work!
Then there were were years (about 25 of them) when 5-6 days a week, I was gone at 7:30-ish and back at 6-ish.
Some did and will consider me wrong and think I should have re-homed him. My husband at that time detested the bird. My current ol' man tolerates him with good humor. No, the bird wasn't responsible for the first marriage's ending!
Anyway, here is what I think made it work.
I moved and got new jobs maybe 5 times or so. BUT...
Every morning, he had at least ten minutes, and every evening, he had 20 or so. I have always kept him on a natural light schedule, in a separate room, so sometimes those times together were in the dark. During the day, he had a big window looking out on something interesting, a television on one of his favorite channels (Music channels, CNN - he loves talking heads), a biggg cage, lots of fun foods, and a few toys that I changed out regularly).
He KNEW he could count on those two pathetic sessions a day. Somehow we both made it.
I'm now retired and times are good again. Side-note... when I first started being able to spend much more time, he was strangely aggressive and jumpy. Eventually we settled down.
I don't know if I am doing a service or a dis-service in even suggesting you get a bird. I do know I can't imagine life without mine at this point.
Good luck to you in making a decision. And welcome to the Forum... you'll get lots of empathy and advice here.
