By no means am I an expert, but I would think that if you are as motivated you can do it. I know plenty of people that have.
Start going to the local investment clubs or wherever and meeting people that have the money. Then learn about a particular market that they seem to be interested in. Bring them a deal that they did not know about and they will fund the deal if the numbers work and it is in fact a good deal.
No they arent going to show you how to do it. No it’s not going to be easy, but you if your as motivated and smart as you say you are I don’t see why you would’nt be able to pull it off. The astute investor was once a struggling salesman or employee at some point.
You do not have the money now, but you can bring value to the table. If you work hard AND smart you will be able to, but it will not be easy and I’m thinking you probably know that.
Also, if you are as driven as you mention above I’m sure you don’t care what everyone else said above. Get out there and do it and prove them all wrong!
