Easy.

اللَّهُمَّ لا سَهْلَ إلَّا مَا جَعَلْتَهُ سَهْلاً وَ إنْتَ تَحْعَلُ الْحزْنَ إذَا شِئْتَ سَهْلاً 

Allahumma la sahla illa ma ja'altu sahla, wa 'anta taj-alul hazna idha shi'ta sahla O Allah!

There is nothing easy except what You make easy, and You make the difficult easy if it be Your Will

[Ibn Hibban]
