I used to play piano and guitar almost daily. I was never great, but I was competent (and confident) enough to play on stage and record some songs with friends.
But, I didn't keep it up.
For the past 10 years, I've been focused on career, family, other things. When I decided to get a keyboard in December, I was understandably very rusty.
I am starting to feel the same way about writing code. After the past two years of running Draft.dev, I'm not nearly as good at it as I used to be. After spending a whole afternoon trying to connect to a remote database, I threw in the towel.
I'm not worried about it though. Just like picking up keyboard again, I feel like I could go back to coding anytime. In fact, I like having a lot of skills, even if I'm rusty on most of them.
Skills stack, and even when you're not in practice on them, they can still help you gain more perspective. I think about this all the time when I'm listening to music. Even though I'm terribly out of practice, I find myself picking up on a single instrument and trying to reverse engineer how the musician played it.
Enjoy having a lot of skills. In different seasons of life, you'll get the chance to use each of them in unique ways.
