I also advise to build relationships very consciously and to remain critical.
Find out what it is that makes you happy and then find people who think alike and whose values align with yours before just entering certain projects because there is some affinity, for the money etc. although that’s just fine. But you’ll be many steps or even a leap ahead if you dare to remain critical - the right opportunities will be there. Then work really hard on developing and maintaining relationships and developing new projects.
Also, never lose touch of your inner child and enjoy making mistakes
