A graduate from the Uni Fellowship of Christians has written a great article about his struggles with being a good manager. There's some really great insights here:

So now in managing I try to remain mindful of two things: in order to do the most loving thing for staff and the organization I need to have a variety of styles and approaches in order to ‘best fit’ the individuals I deal with – not just the most ‘natural’ or easy for me. This is primarily a pragmatic issue. Secondly – and more importantly – I need to be more ruthless and honest about the motives behind my style or approach. There’s nothing inherently wrong with being nice. But I can’t let my likeness for being liked be the main driver behind my actions – that’s actually the furthest thing from being nice in the long run. There’s obviously a place for informality and flat decision making processes but they shouldn’t be a front for laziness and apathy. This is primarily a discipleship issue.
