One thing I’ll say is as I get older it seems like it gets harder to stay connected with people. I don’t mean connected like knowing what they post on Facebook or instagram, but actually hanging out with them and knowing what’s up with their life. You might find that some friends or even some family kind of fade away. Numbers dwindle. You might even come to realize that some of those friends and even some of the family actually kind of suck and you’re better off without them.
My cheap advice is recognize the truly special relationships and fight to keep them. Might be harder to find time as other priorities build up, but don’t lose the people that really matter. I mean that not just for wife/girlfriend, but also parents, best buddies, siblings etc. Maintaining those relationships won’t come as easily as you get older. Give them some focus.
