Honestly, a word of advice:

First, don't lend money to anyone, and definitely don't act as a guarantor for others.

Nowadays, money-making opportunities are scarce, and there are tons of loan platforms.

If someone still comes to borrow from you,

nine times out of ten, they're the type who "can't pay it back."

Once the money is lent out, it's mostly just like paying tuition for a lesson.

Second, don't overestimate your boss's judgment.

Except for a few true tech experts,

most bosses don't care how well you perform,

only whether—you've "catered to their emotions."

Make sure they see your work,

because competence is the foundation, but emotional value is the amplifier.

Third, don't treat too many people as your own.

Let's be realistic,

most people are only good for nodding acquaintances,

not worth deep friendships, collaboration, or shared risks.

Getting too close can easily lead to hurt.

This isn't pessimism,

it's necessary self-preservation for adults.

Stay a bit further from the crowd, set clearer boundaries,

and the chances of getting hurt will really be much lower.
