Lots of advices. On financial side: earn, save and invest. On the career side: learn more and practice marketable skills (like team leadership). On the life side: eat healthy, do sports, don’t stress (or at least relax and meditate), don’t overblow your expectations, try new things and
explore, focus on important things: well being of yourself, your family and your friends; finally, find happiness in simple pleasures of life.
PS. Work on your habits and your relationships. Both self-improvement and quality of friendships and love tend to compound over time, if you regularly invest in them.
