Non-technical, but useful

You can become lethal by developing skills as a non-technical individual, assuming that you have some blend of self-awareness and some method to absorb the world around you.

If you storm through the city during rush hour, managing to solve micro-errands, texting, catching the bus, employing various and personal self-orientation techniques while keeping your head clear and protecting your decision-making capabilities, you are on the right track.

If you believe what you want to do and gradually prove yourself legit, the world itself will shape around your goals. Less talk, more work.
