Sometimes minimalists could get confused whether if one is truly being ‘minimal’ enough, especially for people who just started it and those that practice it for the sake of following the trend. I used to be confused in many aspects, such as whether I have got rid enough of my processions, whether I have kept enough of necessity. The measuring tool is always on the hand of minimalists themselves. I thought back why I wanted to be a minimalist, and I no longer feeling confused. If you do not have a strong reason to be one, and do not think the benefits of minimalism can be beneficial to you, then you should not start it.
I never wanted to be a hardcore/extreme minimalist, I will keep a few extra pairs of socks, a few more of underwear, for hygiene purpose, in case they do not dry off during raining season. I keep things that I wish to use it when I have occasional mood, such as my ukulele, I do not play it every day, but I will not want to go look for one/buy a new one when I want to play it, when my friends visit me to play it together.
I cannot change the past, I can embrace some of them and accept their existence, I do not need to throw them all away for the name of minimalism. I keep things which mean a lot to me, especially things that were given by my family, good friends, though I do not hope my family and friends will buy me anything in future, but we can always spend quality time together.
Remember your purpose of practicing anything so that you will not get lost.
