Being financially unstable can be ascribed to our failure of maintaining a budget. One should know the cash flow, in terms of the money earmarked as savings, investments, daily requirements etc. By doing this, one can very conveniently keep a track of the expenditure, avoid loopholes, prevent financial decline and also, easily focus on investments. Set up a monthly limit and jot down every penny you spend; you could alternatively take notes on your phone or maintain an Excel sheet. So, when you save enough you can further concentrate on doubling the money by investing it wisely. Financial solidity relies on efficient allocation of funds, not a Herculean task.
