[Top 3] What are the top 3 things you can do before you turn 30, to be able to say at 50 "I have made it in life"?

1. Good career

2. Six digits investment portfolio

3. Happy Marriage

But these are just the top three things I want to have <30 years old, pretty sure I will have some smaller goals before 30, I mean many short term goals will eventually lead to the big goals I want.​​​

I think life is rather a process until it ends,

with no defined milestones that define you as a success or a 'winner'. Of course there are goals, f.ex., career or buying a house, that are also important. But can accomplishing these be the definition of successful life? You'll move on and still could be unhappy. What with 50 can be seen one way, could with 70 seen a different way. Also You must live Your own good life, not something peer pressure drives You to do.
