Four Years
I got out four years ago myself and have a strong business now and I too have similar moments of longing for the sky.
I also quit smoking over 18 years ago and occasionally have a desire to light up. Don't do it man. Resist the urge. Perhaps in ten years when aviation has totally imploded you and I can pick up a left seat 747 position for kicks but don't let yourself or family down.
GA is dying and airplane values are dropping like rocks. Buy a Bonanza and forget about it.
