When starting out how big of an advantage is having capital?

[Dentric Vance]

After going back and forth I’ve finally made a decision on the strategy I want to focus on and that is buy-and-hold.  That being said one of my mental blocks is having enough capital starting out.  I realize a lot of things could happen with investments that books won’t teach.  I’m worried about not having the resources to rectify certain situations, and spreading myself too thin in the beginning.  Should I go ahead a move forward and work through that challenge?  Would it be strategic to wait a few months and save at least 10-20k of resources to have for just in case situations?
