Advice for managing "fear"

[Lyman DeAnn-Gaines II]

Just finished Rich Dad Poor Dad, and started reading the Biggerpockets UBG. Kiyosaki talked about fear of losing, and the UBG is already talking about fear.

Personally,  I would say yes I have a fear of losing.  But what i am wanting to ask everyone is, how did you overcome your fear? What did you do? 

Yes it's the way that worked for you,  but I would like to hear your stories and hopefully emulate if it seems like something that would work for me too.
