How to kindly be anti-social?

I think the word you're looking for is un​social

Well you must be doing it right if your on TSR for starters ...

You're quite right. The misuse of terminology that plagues the area of London I reside in has taken its toll on me.

Step 1 complete. Although I still have friends who are adamant on making me venture to their usually pathetic and unproductive daily activities.

seems I was wrong too- the word I was looking for is unsociable

So much for having GCSEs in English.

Stopped reading here.

Your jeopardizing your future , abandon these fools and their trivial tastes , they will only weigh you down.

I whole heartedly agree. Although my mum is quite supportive of the concept of having friends. Imagine.. she even wants me to get married someday. I'm thinking of cutting off ties with her, although, I could do with the financial backing which she can readily provide. I'm in some sort of conundrum on this decision.

Same here , I can sympathise with your current predicament.

My personal solution to this long term dilemma is to use my mother for her assets while I secure my future in all means of the word , once I am in a stable financial position I will burn the bridge so to speak , and lose this non profitable asset.

If you keep saying "no" - people won't really know you, and hence will stop asking you out. Although you'd probably become lonely with no friends.

I'm due to start university this coming September. I was wondering if anyone could offer any advice as to how to kindly tell current friends that I no longer wish to maintain contact, due to having study commitments.

Also, in general, how would I stay clear of unnecessary friendships during university which may have a negative effect on my performance?

I ask this because I've heard of many stories where people didn't get the degree classifications they originally aimed for and blamed it on socialising, I don't wish (nor wish to take the chance) of making the same mistakes. Thank you in advance.

tl;dr: How do I go about being a ghost, without being rude, basically?

OP, I would suggest that having friends will have a positive impact on your mood, and thus make you much more likely to do well.

Just kindly reject any invitations and they'll get the message.

But I don't think having no friends is healthy. Why don't you join academic clubs/societies at your uni so you can make new friends. This will prevent the mental health issues that are likely to arise as a result of having no friends, and being around like-minded/ambitious people is likely to motivate you and make you achieve more.
