Who has every heard of anyone doing really well at something (sport or business) without the prerequisite learning, ongoing training and practice?
An athlete trains hard all the time to keep in peak form. Ongoing training is key part of continued success without it arguably failure is given better odds.
Property investment also requires the initial learning ongoing training and active participation in property deals for you to stay at the top of your game without nasty surprises.
Participating in relevant discussions with other active property investors, actively reviewing real property deals and of course doing your own property deals sets you up to succeed every time.
