You never know how much work it is until you really have to do it yourself. During my bus project I really had to learn that 'only this we need to do' and then we are done isn't that easy... It requires patience and also tedious work to get great results. You need to think and plan the process - if not you will mess up. Believe me - we have had situations where we wasted days and had to redo it all over again. But hey this is how life is! You make mistakes and then you get up and learn and keep trying!
