it is true – you can’t have your cake and eat it too.  sure, you can try – but it is not advised.  you can run it through your mind many ways in which you can have your cake, etc. – and you can come up with a solution most of the time.  but in each of those solutions to have your cake, etc. – you inevitably hinder or hurt something or someone else.  it will always be at someone’s expense when you attempt this.  this will burn a bridge, leave a very negative impression and give you bad karma – it will come back around.  so you need to make a choice – the cake or eating it.  don’t be greedy – make a choice and live with it.  the choice you make will always be better than trying to have both.
