How do I enhance my real estate investment career

[Spencer Simon]

It's another newbie with big dreams but tiny pockets at present. I'm curious to know what's the value of seeking a RE license vs home appraisal vs contractor license? I understand Kaplan offers all three. I believe in investing in one's self when ever possible in order to gain better understanding and effectiveness , but are any of these pursuits really needed from a buy and hold investing angle?
