Always be on the lookout for interesting job prospects, and realize the value of working 2 or more part time jobs for its variety of experience and its ease on mental health. Obviously this depends on what you want for a career. You can't get away with being a part time beginner lawyer but I just know I'm always happiest when i don't have to go to the same place and do the same fucking thing 5 days a week. Especially if you can make these jobs different- one physical, one mental/emotional. And, related to this, actively look for weird jobs. Exchange willingness to work hard for someone teaching you the ropes of a new thing. You'd be surprised how much there is to learn about some seemingly simple manual labor job, for example, and in the coming economy, it seems like it's way better to be dynamic and multi skilled, with established social networks in a variety of fields, than to specialize in something ai will probably be doing in 10 years.
Remember to try abd ve honest with people. Sometimes you'll be thrown into ugly horseshit situations where there is no clear answer on what to do. Cultivate a habit of being responsible for your honesty and impact on other people. It really makes difficult times in life much more tolerable when you can say, at least I was honest, and I made an effort to not hurt, of even help, other people. This is a selfish thing, it makes your life easier.
Maintain relationships with your family. Do your best to find a way to keep the lines of communication open. Forgive old bullshit, keep connected. Family is extremely important and this becomes more apparent as you get older. If you're blessed enough to have a decent family, stay connected. Even if it's a shitty family, find a way to stay connected at least in a way that you can, whatever that looks like.
