You'll need to complete your retirement strategy before the deadline. It's not something you want to wait until the last minute or even when you're in your final years of work before doing, no matter how much you think you have saved up. You should be able to start this process as early as possible so that by the time it does come around, you'll have a plan in place and won't have to worry about where your money will go.!
In order to start this process, you'll have to complete a financial analysis using your monthly income and expenses. This can help you determine if you will be able to retire at the same level of lifestyle that you are currently living, or whether it would be beneficial for you to make some changes now in preparation for retirement. The earlier you begin this process, the easier it will be on you in the long run.
