No matter what our age, there is an instinct to see those who are younger as inexperienced and foolish, and those who have come before us as outdated and of little use. That instinct can rob us from valuable learning and experiences on both ends.
Seek to gain knowledge from an older generation. No, they probably don't know what Instagram is, but they have lived through decades of hard work, child rearing, and career building. Their wisdom should not be taken for granted and their experience cannot be bought.
Also seek out a younger generation. You may learn a thing or two, but more importantly, mentoring and pouring yourself into someone willing to learn is infinitely valuable. It will help you understand things you didn't before, and solidify the lessons you learned throughout life.
