Are you a born loser?  Gosh, I sure hope so.  
Property investment is a skill not unlike skiing.  Before you can descend the slopes with nothing but stylish élan, you are going to have to face-plant into the snow a few times and learn to get up.  Even then, there is no guarantee that you are not going to fall down a few more times.   It is through falling and learning to fall correctly that you become a true skier.  Same could be said about investing in properties; the longer you stay in the market and the more mistakes you recover from the more likely you are going to reap long term benefits from your commitment to your financial future.  
The trouble with investing is that many of us (especially during a market upswing that is further fuelled by media hype) get into it expecting to be nothing but successful.  Confidence is one thing but when you start believing you are more likely to spot the next goldmine than the next investor is when you should read about the Lehman Brothers.  ‘Cause hubris always wins in the end.  The Greeks taught us that.*
