why do postive thoughts become a reality.

I had a very interesting talk with my dad the other day. It was reading the power of positive thought. We might have heard many a times that positive thoughts becomes reality. If we want something to happen and if we think positively about that it will happen. Why is it true. My dad and I had a long conversation about it but I decided to summarize it.

If we want something to happen. Obviously we will do some work to get that. By thinking positively about that goal to be achieved we will develop a positive attitude towards that goal. So out approach would be positive as well. All the actions we take to get the thing done will be steering us towards the achievement of the goal. If we face any obstacles we will not be discouraged by these. All our deeds will be geared to get the thing done. But what if we have a doubt in mind. Every little obstacle is seen ten times what it actually is and we tend to lose confidence with every little trouble we had to face overcoming the obstacles. So postive thoughts leads to positve attitude and with this attitde we can get anything done and a doubt will slow things alot.
