Examples of concentration in a Sentence

1. Deodatta V. Shenai-Khatkhate:

   nous, êtres humains, sommes distinct et unique dans notre capacité à rêver, puis efforçons de transformer ces rêves en réalité. les rêves la nuit, vu avec les yeux grand fermés, ne sont que des illusions créées par des impulsions électroniques et des vagues au sein de notre cerveau et le système nerveux central. au contraire, les rêves vus en plein jour, les yeux grands ouverts, sont les plus importantes, parce que nous pouvons poursuivre ceux diligemment avec concentration totale de notre cœur et de l'esprit, et bientôt les réaliser dans la réalité. à mon avis, ces rêveurs, croyants, poursuivants, penseurs, inventeurs, des innovateurs, des planificateurs, des stratèges, et les acteurs sont ceux qui changent notre monde, et font de mieux en mieux qu'il ne l'était jamais. notre monde a besoin des milliards et des milliards de ces rêveurs qui mèneront l'humanité à la perfection. donc, ne laissez jamais vos rêves disparaissent ou meurent, surtout ceux que vous avez vu au grand jour, les yeux grands ouverts. aller après vos rêves, sans relâche avec le plan parfait, de la passion et de la persévérance, peu importe ce que les autres disent ou font. bonne chance à faire vos rêves.!
