Happiness comes when we stop complaining on what we don't have. "I don't have this, i don't have that, I don't have what others have." Instead of complaining, we find ways to achieve it. If it fails, we are really sure and yaqin that Allah swt has a better plan for us. Strive for what we want to achieve, tawakkal and do'a. Allah swt has never been cruel to His servants. Everything happens for a reason.
May Allah swt increase our sabr and taqwa. May Allah swt forgive us. May Allah swt reward us with Jannah in the Hereafter. InsyaAllah.
Allahu Ta'aala a'lam
