The same for me, I've always wanted to be a pilot. It was and still is a slippery steep hill to climb and you'll never reach the top probably (exams keep on coming).
But last week me and my training captain were flying back from a platform above the clouds with the sun setting..........It just makes you feel great.
At other times when you're solid IMC enroute to a rig at 200 ft radaraltitude it's all very intense and exciting/terrifying.
Every day you learn a new thing and people who are pushing retirement keep on telling you that every day they still learn something new.
Great job, eh! Everyday when you go to work you have a smile on your face!
