Learning from others
Like-minded doesn't mean people who agree with you on everything. It means people who have the same overarching aims in life. It's not necessarily an agreement of whats, but whys. You can learn a lot from like-minded people.
Life is short. With so little time, if we have any hope of learning anything of value, we will likely need the assistance of those who (probably through this same method) have learned something we do not yet know. You've heard the cliche that you are defined by the five people you spend most of your time with. Whatever the precise number, the fact is the better the people you spend your time with, the better you are likely to become.
Juries
As the willingness to abide by the impartial rule of law fades among the majority, you need to remember that if you ever end up in court, your jury will be composed of people who live in the county or city where you reside. If these people are predominately of the average type, you run a high risk of being judged not by the actual law, but by increasingly perverse cultural norms. Do not underestimate the odds of being before a jury, even if you are a law-abiding citizen. The fact that the majority of people believe that it is ok to do wrong things for the sake of their ideology is something that should cause all good people pause, because all good people are targets under their ideology, even if they have done nothing morally or legally wrong. I wonder how often it is possible to get a fair trial in America today. I really think it's that bad already.
Actually getting things done at work
Light cleaves to light. All intelligence builds on all intelligence. Your success at work will depend on what those you work with can accomplish. The modern world is too complex for any single person to do much of value alone. No matter your work ethic or intelligence, your professional success will rely on the work ethic and intelligence of others. If you work with a bunch of boneheads, your organization is going to sink like a stone, particularly in the economic challenges that are upon us and may prove to be far more lasting than most expect. I have noticed many bright people moving into smaller organizations--often self-employed--where they can enjoy a concentration of people who are not lazy doofuses. It's getting harder and harder to find this quality in large or mid-sized companies.
Recharge at home vs a constantly draining battery
Your home ought to be a refuge from the world. Too many people are strangers in their own home. This is probably the saddest item on the list, because it's typically a situation that is too late to change once one finds themselves in it. This is yet another important bullet in the long list of really important decisions you need to make as a young person, but are almost guaranteed to lack the wisdom to make well at the time, and underscores the importance of having wise older mentors in your life--which seem quite rare today.
