history: An employee that I helped train, just became a manager and is going to be doing some really big projects for the team I feel so gratified and rewarded right now.  It feels like it was all worth it That's great! What made you feel rewarded?
current: This employee that I helped train when they first started is now becoming a manager.  I feel like I was instrumental in helping them get to where they are now.
next: Oh yeah I could see how that might make you feel that way. Is the employee grateful for your help?
