Don’t treat your business (which could become your livelihood) like a hobby… You need to constantly develop yourself and beyond that, LEARN and master some “business skills” and “business sense”.
You need a sense of direction and frankly… know your “business stuff” so others don’t walk all over you and take advantage (I’ve seen this happen to well, myself, and other colleagues).
Here I’ll try and share some tidbits of what’s worked for me. Enjoy 
Hey, kilelr job on that one you guys!
