Well, I don't know about others but these questions left a complete mark on me.
I stopped for a while and tried to configure after applying these questions to myself.
Specially that one about "Am I wasting my time and energy on unproductive or negative things..."
Well done mate. This will work for so many individuals who are reading this post.
That one you picked out is a huge one and if answered honestly and then if the answer inspires the right thoughts, attitudes and actions great forward motion can be made in the opposite direction...meaning positive outcomes.
I noticed also the phrase you have on your profile, "undergraduate in search of perfection."
Ok, I get it...but here's the thing...perfection doesn't exist and searching for it is a waste of energy and time; you're best to search for ways to find continual improvement...it's more rewarding, more often, and will carry you forward towards better results. Just a suggestion.
Yup, but if you want positive outcomes, a great critical thinking is required.
And you get that phrase very well mate. Actually when I search for perfection in something I continue to improve myself to achieve that perfection and since perfection doesn't exist but it benefits me in continuous improvement.
That's ok, keep looking for perfection then. Good luck.
