I'm nervous because I've never had a business before and I still have a full-time job as a cloud solutions architect, which I'm really passionate about - so hopefully it won't be my golden handcuffs that may prevent me to thrive as an investor and  I'm excited because of all the benefits and freedoms being a business owner offers, one of which is to connect and collaborate with forums like this and people like all of you, where I can both learn from and hopefully share later as I develop more experience. :-)

This drives us to have a little higher barrier to scaling my investing business, however I am trying to go far, not fast.
