Well, I'm 43. Not sure if that makes me an "old guy" or not.
That said, even at this "middle" point in my life I recognize that there were two (well, three in a way) forks in the road where I made decisions that I wish I hadn't made. These have left me living in a place I intensely dislike, and in an industry I could really do without.
The first and most critical such fork occurred 2 years after I graduated from college. My parents let me stay at home as long as I wanted rent-free. In that time, I took a job in the software industry that I didn't much like, but which paid pretty good and wasn't very hard for me to do. Upshot was, after two years of that I was bored but I had enough money saved up so that I could either:
- Pay off all my student loans, and then be free to go see the world or go back to school or do whatever I wanted to do.
- Buy a house, buy a car, be in debt up to my ears but pursue a "normal" life (as defined by my family).
Long story short, I picked door number two, which meant that I had to continue doing the job that I didn't much like, which meant being stuck behind a desk bored out of my mind most hours out of the day. I'm still stuck in that same basic job.
If I had it to do again, I would have rejected all the materialism and run off to see what the world really had to offer.
The good news is, it's never too late to correct these kinds of mistakes. You just have to try a whole lot harder to get there at 43 than you do to get there at 23.
And the most important point of this post is that, of course, it's nearly impossible to know what you really want to do with your life when you're 23 years old ....
I hope this helps.
(BTW, they aren't worth elaborating, but the other two "forks" where moments in my life when I had the resources and the opportunity to ditch the "normal" lifestyle, but I didn't do it for various reasons. Once I was scared and another time I was lied to. I should note that both opportunities involved women, which just goes to show how much they can mess you up.)
Cheers.
