For people who want to retire early, he/she will start to wonder when he/she can quit the full-time employment. The same also applies to me earlier. I realise that there is no need to ponder much on this question. The answer can be easily found through simple assessment. One just needs to keep his/her need simple and want few. He/she can retire much earlier than many others. I guess that this is some form of paradox which people will encounter during their journey to Financial Independence And Retire Early (“FIRE”). This is the sort of mindset in which one will need to overcome in the journey to FIRE.
