If you wish you had one skill....
Okay here's the deal. I'm looking to invest in my first buy and hold property very soon and expand from there. I work as a nurse and I like what I do, it pays the bills, I have excellent job security and I can literally pick up and go ANYWHERE I want! Eventually I want to build up enough of a portfolio that I can transition out of nursing or maybe only need to work part time as a nurse and work more hands on with my investments. I'm fairly handy- I've done everything from laying flooring and carpeting, tiling, grouting, hanging kitchen cabinets, hanging and finishing drywall, roofs, fences, landscaping, minor electrical and plumbing repairs, etc. I'd like to maybe pick one skill and really perfect it, maybe get certified/licensed, something like electrical, HVAC, etc.
So I ask- what skill set do you really wish you had? or what skill do you have that helps you the most?
