When preparedness meets with opportunity, success is inevitable.
How then do you prepare? You do this by first Identifying what you need to achieve. Set the time frame to achieve it. Then create a plan and a back up plan for it. Work on the plan and work hard at it whether or not you have talent for it. Dream about it. Ask God for it and about it. Talk about it by verbalising either to yourself or to a trusted person. Visualise it and of course expect it to happen.
Set a time frame for it because time and tide wait for no one. The clock never stops ticking, remmember.
Do not wait for it with arms folded but with a prepared mind. When you see it happen you will not miss it because you are fully at alert and expectant.
It is true that opportunity knocks but once but a fully prepared person can knock on opportunity's door by just walking into it.
This is what most people call luck which really is not luck. It is God that makes the impossible possible.
