Dreamers are all talk and no work. They tend to plan big but failed to start small because they are too consumed of dreaming and planning things only to end out that they won't be able to do a thing.
Never forget that who have succeeded today have started from a scratch, so they have been into failures a lot of times but they are strong enough to overcome them since they always try to put everything in action, than just to stay dreaming and yet fearful to put them into action knowing they are afraid to take risk and are afraid of losing. And with fears comes procrastination, which is why a lot of people fail because their efforts are not enough, or they are just simply lazy to start everything thinking that if they don’t got the chance to start today, there will still be a lot of chances that will come and will provide them the same opportunities they’ve seen today.
I agree most of the successful people started from a scratch, the difference between a successful person and a dreamer ( the one that full of idea but no action) is that a successful entrepreneur never give up on his goal while the latter one is too lazy or afraid to start to work out his dream due to being afraid of the risk or the wants to walk in a smooth path which is not possible when dealing in business matters.
