If you’re having problems with affecting your sabr then purchase a 1000 piece jigsaw puzzle. I’m not joking here. Test yourself. See what happens.
Do you give up because of it’s difficulty or do you realise the benefit in completing it and thus persevere with it? And when you’re missing the last piece do you yell at the maker of the jigsaw puzzle or do you giddily smile? And if you do in fact gain all the pieces and align them properly then who do you praise – The One who gave you intellect or your self?
Have a try and see what lessons you learn.
