In any plans you make, it cannot be static.
Regular review is required because priorities and circumstances change.
For instance, a change in job that requires you to travel frequently means that any investment you make has to be more “autopilot” than before.
Another example is if you or your spouse decides to spent more time at home with your children, it implies a reduction in disposable income. Thus, your cash flow is lowered. Of course, there are many other examples why plans change. Life is full of changes and surprises and this makes it interesting.
Financial review can be done by yourself or by your professional financial planner. The latter can be of help to you if he or she previously did a financial plan for you. The benefit of reviewing your own financial situation is also dependent on how much long-term contracts products you have bought. I am against signing up for long-term contracts investment.
