nice_chap saidI admire anyone who can claim to be a jack of all trades. Sure, it's great to have a passion that you dedicate your life to and if you make a successful career of it, then that's amazing, you get to be a shining example to others that have similar career goals. But I certainly don't devalue anyone who doesn't have one particular passion that they want to pursue, and end up focusing their energy on all kinds of different jobs and activities. These people get to have a life and experience all sorts of things and meet all kinds of people and they have lots of stories to tell, and this makes them interesting.
I failed at making a career out of the subject I thought I was supposed to be good at. And because I had this particular ambition, I had a very narrow minded view growing up, I couldn't see myself making a career of anything else. And it didn't work out for me, so I'm not really a master of anything. I'm a jack of a few things.
An interesting view I hadn't anticipated. But becoming a Master of a single thing was something I actually feared. Even as a little kid I never wanted to be strapped into doing primarily just one thing for my entire life. And what if, as you seem to be saying about yourself, it doesn't work out?
And so I kept hesitating, dabbling in many things, until time simply ran out. Fortunately I had family support, which relieved me of the pressure of having to choose quickly or starve. And I always had some small income of my own, even if it's meant at times I've lived at subsistence level.
I stumbled across the Army, only thing I ever did happily, and perhaps not too badly. But then almost every day was different. Sure I had specific training and a career title, but that didn't stop the Army from assigning me to every kind of unexpected & unrelated job, and locale, that I had never dreamed I'd do or see. I found it fun! And adopted for myself the personal motto of "Thrive where you're planted".
I'm not sure I'm a Jack of ALL trades, that's just a saying. But I'm pretty handy at almost everything I try. I'm constantly approached by friends & neighbors to fix all kinds of things, solve all kinds of problems for them. People will say: "Give it to Bob, he can always figure it out". Whether it's fixing a kitchen appliance, or a car, or a traffic ticket for them, all things I've done, and much more.
I like the challenges, and the minor fame I receive from solving them. But also hate the disappointment when I fail to deliver. So that lately, as I'm aging, I'm increasingly reluctant to accept these requests. Unless I can see that it's a "quick kill" I leave more complicated problems to others. Making me more of a Jack of SOME trades, of my own choosing.
