In life many things are unpredictable, for example there is a need for a spur of the moment because we are sick so we have to be thoughtful to divide money, advice I was 50% for saving and 50% for investment.
That's right, you need to think in advance about unforeseen situations when money may be urgently needed.
For unknown reasons and unseen cases we must save money as well as keep up investing the money. I think 50% savings is a bit too much. I suggest 10-15% savings at most of total monthly income. We have to divide the total monthly income based on our own needs so its better to experiment and list out the basic needs first and then divide the money in that manner.
