When Investment Returns Matter
The goal of financial planning is to build enough assets, by the time you retire, that the income earned from investments (including pensions etc.) will provide you with your desired lifestyle, without the need to get out of bed and go to work.
Simple, right? All other discussions relate to the strategies you can use to build your wealth to the point of Financial Independence or beyond. For true wealth, think about acquiring capital or assets beyond supporting your standard of living.
