always on fire

we continue again on people of no 2 stories.
many times i was in that position but luckly enough it was very small situation.

it was always a very hot position because fire coming from top and bottom.
we also cannot make good decision because no 1 want to plant their agenda and bottom want us to fullfilled their needs.
that where no 1 always strengtened their position and no 2 always had been given boot out.But some no 2 manage to make them relevant and survive.
i also lucky manage to be in no two without any problem so far but always hate this position

classic example on this was Dr M.
he was a very good no 2 to husien onn.waiting and hold on until he got chance.
we not talking about how he got there but how he manage during that time.
something to learn here?
unfortunately few of his no 2 not like him and cannot manage the situation and was boot out.

another one was tun razak which also very good no 2. he even manage to hang there for avery long period and become the only no 2 to T.A.Rahman

but if we look carefully on our Nabi Muhammad S.A.W management, he dont have no 2 eventhough people always name saidina abu bakar as no 2. but Nabi never mention anything. he have four no 2 which every person have different character and strength.
people always argue that we cannot do that in current scenario.
but why cannot? did anybody try before?
this four also know how to play their role well.

why this system so succesfull? what special about it?
