There are so many early retirees now, visit any gym in the mornings and you will see them, they go walking, golfing etc etc , look around your community, typically aged 45+ and you will see them, these are the first generation where their jobs for life ended early for varieties of reasons.
As I stated earlier in the thread you plan as you are clearly doing, you will be fine, I have walked the road ahead of you, financial planning is essential as are in my view performing generating assets ( property in my case )
Never mind the Nay Say ers you plan and you execute, this thread is valuable to others that read it, they think of their own situation and may never post, you are on topic for sure.
Same for any of us, plan to fail - fail to plan..;-)
Oh finally beware of people in suits promising absolute returns and advocating various investment strategies, I worked in financial circles for nearly 30 years and in that time I have learned much, foremost is that those experts wearing various badges of honour and that don a nice suit means very little, buyer beware when it comes to any investing for the future, in my case I prefer to paddle my own investment canoe but that is just the proven cynic in me. I avoid commissions, payments to advisors and so on, each to their own and all that..the joy of AAM is that you will invariably get good stuff from replies after a meaningful query.... when a filter is applied of course.
