It is not possible, but also it is not good for you that all be done according to your wish. Many times, your thought is lost, your wish is vicious and your will is selfish. . And the all-knowing God sees it, even if you don’t realise. This is why he doesn’t allow that all your wishes be fulfilled, so that your soul – your biggest treasure – will not be hurt. Therefore, entrust yourself in the hands of God and into His will.
The best way to gather your thoughts is having a main one that helps you to recognise the others, and to cast the evil and support the good ones. The easiest way is this prayer: ‘Lord Jesus Christ, Son of God, have mercy on me, a sinner!’ We say this in order to be able to be steadfast in good thoughts.
