“Man gets what he strives for”.
– Qur’an: 53:39
So that makes it easy for us. Primarily, identify what you want to achieve in this world & the hereafter; I mean the specific goals. And then, just work for it. Just work for it. Work for it. The rest will all be taken care by the Lord of the Universe.
And if your time on earth comes to an end, even before your goals are actualised, then know that your Lord has already rewarded you for the good intentions you made. So a positive mind is always a winner, ALHAMDULILLAH – All praises and thanks be to Allah.
Hence you are an achiever, when you work for your objectives.
