Is it time to start taking action?

[Maykol Au]

Like most of us start out, I have been working a W-2 job for a few years and saving up to eventually kickstarting my real estate investing. Now I am at the point that I feel like I may have enough money to get started but I keep telling myself to save up a bit more before diving in. Am I just using this excuse as a scapegoat? Currently, I have about 15k cash and another 25k invested in the stock market via ETF's. Should I consider cashing out on the funds invested? 

Would love to get some feedback and hear what you guys think. Thanks BP!
