Remember back when you were a kid? You would just do things. You never thought to yourself, “What are the relative merits of learning baseball versus football?” You just ran around the playground and played baseball and football.

Source: Screw Finding Your Passion
I am so feeling this article right now. I have dozens of hobbies and passions (long time readers will already know that), and they all take their turn garnering my full attention when the mood strikes. I have always felt a little left out when folks find out that they are “insert discipline here”. I am me. I am a Jack of All Trades – screw being a master of any of it.
I love what I do in the fits and spurts that I do it in. I am suddenly feeling inspired to write up a new bio. You can just call me Jack.
A Less Travelled Path 
Renaissance Men (People) … they also had a lot of interests / passions. I don’t think they started out as experts, either – that came with age, education and experience. I think polymath is another word we came up to describe such people. If you are not yet a master of your particular interests, perhaps you are a polymath who just still uses your fingers to count every now and then? Or perhaps a philomath? Either way, I think it’s great that you are embracing more than just a single interest – doing so has a way of rounding out one’s character a bit more. Instead of Jack, perhaps Andreamedes Paganova da Witchi 🙂
