You're doing it wrong if you think programming for work is about the code being a means of expressing your inner soul. The most successful professional programmers derive their enjoyment from achieving business objectives, like making products that users love and improve the world.

If you want to express your soul in your code, do that on the weekend using whatever language you want. Trying to mix these motivations is a recipe for disaster.

Honestly, just find yourself a project and just Go for it (sorry for the pun).

The syntax is easy enough you can start coding just after having looked at basic examples.

Personally I actually like Go because it's so boring.

I tend to see languages more like tools rather than valuable knowledge I must learn, so a simple yet powerful enough language is a perfect fit for me.
