"Keep big ambitions; moderate expectations and small needs "
There is as much to be desired than our imagination is able to think. We are able to build a successful life and we must imagine it huge and very positive.
We should have moderate expectations of success, always have some pessimism in our thoughts while taking in hand a very high self-esteem. You need to think of mistakes without them blocking you, to study and have prepared an alternative exit plan.
Our vital needs should be almost minimal and not be caught by debt or overspending needs. If something goes wrong we will always have the advantage of not needing to much to survive.
