In real life, many paths seem to be "prearranged": it depends on who knows you, who you get close to, and whether there is someone who can help you pass on a message.
Choosing to move forward in the field of graduation, you do not have to explain whose connections you have, nor do you need to prove how good you are at socializing.
The only two things you have to face are: your judgment and the rules you set for yourself.
You don’t have to miss opportunities because you are not good at socializing,
nor will you be pushed out because you don’t like to socialize.
If you do well, your results will naturally prove you right; if you do wrong, reality will not be polite to you.
It seems cold, but it is direct and fair.
