Let us start with this.How you know the opportunity. There should something called aim. The aim which you are having will make you to spot the opportunity.
Again Let us start with aim. If you have aim in your life , you must try to enrich by reading , writing , talking and visualising telling that you are going to reach the target, that is aim.
For example, you want excel in hubpages. This is aim. You have the opportunities in front you. If you are not going to read the whole hubpages instructions you are going to struck at one place. Secondly if you not going to write , you may not be knowing your strength, that is score. Third thing, if you not going interact in forums or questions and answers , forget about improvement.And then comes your visualising. Visualise where you reach. Do not afraid, to grab the opportunity you must patience by doing your activities in a regular basis. Not in hurried manner.
Then you will never pass the opportunity. So , let us start aiming and activate. Wait for the opportunities. If you do in a organised manner , the opportunity follow you. Not you wait for that.
