Spoiler alert: society has already defined the path to a successful life for you. Nothing for you to do except follow the instructions and don't deviate. In case you missed it, here's the plan:
Get good grades in high school, graduate from college, land a good job, get married, buy a home, have 2 kids, climb the corporate ladder for 40 years, retire at 65, live happily ever after.
It’s not a terrible strategy. It even works! Countless people have followed (are following) this plan and they lead perfectly happy, content lives. Although the major milestones are predetermined, at least you get to fill in the details. For example, you get to choose which college you go to, which cars you want to lease, where you’ll live, etc. etc. But the general plan is in place and anyone that deviates from the norm is, well, abnormal.
So just stick to the plan and you’ll be fine. All it will cost you is your freedom.
