I think most of us would either work in a team or manage a team of people, and sometimes the hardest thing can be to try and motivate them and inspire them to be the best they can be. Some people may take the stance of “well if I can do it, so can they” and sure they probably can, but how they achieve it is different, and generally someone flashing their successes in your face doesn’t help with your own motivation!
What I have found to work well is to show them how great they are, and build on that each time you give them another task. It will differ depending on the person, where as one might only complete a small task and feel pretty darn great about it, another might carry out a 6 month long project. But that doesn’t mean to that individual person, that the achievement wasn’t something special.
By showing them how amazing they are, I don’t mean that to be a “job well done” followed by a pat on the back, I mean actually showing them, they will continue to be inspired and achieve great things. For example, a staff member created a new report for clients which provided 100 new data points and allowed them to do more in depth analysis, but not only that, managed to automate a lot of it which halved the time it took to generate reports for clients. It’s those kinds of tangible results that show them they are amazing, and that’s the kind of feedback I like providing to my team.
