I read with interest on a blogger who stated that one should stop believing that privilege is the key to early retirement. I agree with his view. He mentioned that early retirement can be achieved by anyone regardless of his/her current remuneration.
I am of view that another factor will rely on the spending of one. If one can reduce his/her spending to a significant amount, there will be lesser investment portfolio which he/she needs to sustain his/her lifestyle without a full-time employment. This comes to the point of flexibility in which one can be open to the expense. I use flexibility in my daily life circumstance. I am happy with the minimalist lifestyle. A simple meal with plain water is sufficient for me.
To each of our own.
