Dear @chbartist sir!
I agree with the use of marginal effects. A single habit or monthly months to do not include any habit, but continuous efforts are necessary for that. It is not necessary for a short time. The keypad of mobile is rounded by the touch of the iron, which we cast in the bus, in the day, we just get rid of the iron rods in some days. The saying that only a little effort can be achieved great things. Great things to get great things, we have not passed us from great length, but our effort should be to be considered to be a few minutes or only for a few minutes.
Thank you for your continuous inspiring articles.
