If you make something a habit, make it easy to access.

James Clear talked about this in his book: that habits can easily be formed when you make them accessible.

And so when I am in small rooms or so, it just helps to keep everything minimal and reduce clutter.

This is exactly my point and reason why I find it difficult to leave my place and stay at my parent's place. The small space does not put me in the right state of mind.

This minimalist tendency of simplifying my possessions and keeping them in order sometimes makes me let go of things.

I think we are a lot alike in this aspect and definitely many others. My mum always talk about how I gave out most of my possessions after I finished my ND. I just felt that it was not needed, though might be useful in future, It is best to give it to those who need it now and when the time comes that I need it, I will buy it.

It is better than taking the stress to carry it home, not having enough space to keep it and ending up leaving it laying around.
