The knowledge of having the current withdrawal rate of 2.59% in correlation of the annual expense and investment portfolio makes me feel confident that I do not have work for the rest of the lifetime. While I do take some form of part-time employment, I know that this is subject to my desire (want to do so). I think that this is good for oneself. One will be happy in the course of the life journey. I know that there is a need not to increase the unnecessary wants which will increase the annual expense. I know that I can do so with some form of buffer and it is up to my discretion. However, I have developed the minimalist approach and hence, it is unlikely for me to increase the expense by a big extent.
