One thing that affects the level of productivity of some is their level of commitment. Initially they put so much energy, fuel and determination into their tasks, but as time goes by, the energy dwindles. Nothing good comes easy, but it does come when you do things the right way.
Importunity in that opportunity, persistence against every resistance is how you need to get by doing things in order to get the right results. Start well, continue better, finish best. That is God’s plan for you.
