Take an example of a seed, it needs proper amount of water, soil, sun and air, and some nutrients, and if it gets it properly it will nourish well, it will nurture more better, and it will look good and healthy, these are what appropriate things are for seed, what if any of these things are not the way they needed, or what if ground is full of weed, they will suck all your nutrients and deprive you from your nutrition and will let you rot, same is for the group of friends you keep.
And the best thing one must do is cut of the weed first and remove them so that this plant can grow and add some symbiotic organisms which might support you with your nutrients.
Its just the same thing, i am having, just a month left for my semester and all are coming to me asking to teach them, to help them, asking if i can support them and teach them just important thing, you might say this is a nice thing, you would be revising and learning in this way but seriously its not like that it more or less waste of time, cause they just need is shortcuts to study, just key point important thing, that i mark for them so that they can pass, i am sick of these people
I dont want them any more, i just want to learn and need some space from these people.
