Apart from the risk associated with the uncertainties that comes with retiring early, after retirement, it is always as though the next point is death of you don't make proper plan for what productive activity you should be doing after retiring. for me, i don't make a big deal out of early retirement because in the process of working, i get to become really engaged which makes life less boring. it is not as though it is a bad thing to set early retirement plan most especially knowing that you won't always be as strong and relevant as you are at your prime. you should do it but that should not be the whole essence of life. while still working, you could invest into an asset that will serve as your retirement plan or some sort of a budgeted amount for our luxury if you so desire.
But we all know that it is better to take does risk than not wanting to try anything out at all and I don't see anything wrong with retiring early, there will be enough time, for you do venture into other things, and no matter how productive you idea is anything can still happen, so we have to decide exactly you want to do and even if it does not work there is always enough time for you to invest, and those that are retired early are more focused because they will need something to rely on because they won't just make a reckless decision when they know the out come.
Somtimes we have to consider, I know how young people want to give it there all and this is what makes it more intresting because, it is usually very easy for young people to do bussiness with and their is no way that it won't go well because of the kind of insight that young people have, and before the retirement I will better start investing early that is what safes us a lot of things because by now you want to retire and no plans yet then that is very bad.
