It’s evident that successful people always have a network of others to support them on their way, and they are usually very deliberate about who these people are. No-one gets to the top on their own and no single person can give you everything you need and want. Your bestie will pick you up off the floor and wipe your tears but is he/she going to give you the hard truth about work? A mentor will inspire your learning and performance, but who is going to hold you accountable in everyday life? We are all better off for building a supportive tribe and minimising our contact with those who drag us down - but how do we know who will truly enrich our life?
