What you concentrate on expand

I have been reading this theory quite some months ago but a recent event seems to trigger me and wondering perhaps the theory was true after all. It is said that "What you concentrate on will expand". It is said that, if you concentrate on working on opportunites, more opportunities will come to you while if you keep on thinking how much problem you have, more problem will be coming into your life.

Recently, i was thinking a lot about a game i plan to play. I was thinking about playing harvesting this round and plaaning on growing some plants in the game. After quite a few days, i was somehow got involve in parting some of my money for a good supporting cause. Although in the end i had no idea whether i was actually supporting the right cause or supporting the salesperson income. But to my surprise, what i did get after the supporting was a .............."Seed" .

Perhaps it is true that what you concentrate on will expand is true after all.
