Make initial a decent propensity, next push on to make a decent way of life.
I don’t know how precise 21 days and 90 days are regarding making a propensity and way of life individually. In any case, I do concur that you certainly require consistency and time to make it. We regularly heard saying like, “starting now and into the foreseeable future, I will change in various stuff… “, yet come the week after, he has returned to his previous self. Not overlooking half a month, he rehashes a similar cycle. These are common situations where years after the fact, he is as yet a similar old self.
Creating a good habit/lifestyle can be in terms of being more hardworking in his/her work, be more health conscious in their diet, or simply relationship building with your loved ones. Take the effort, time and CONSISTENCY to build it up to be part of your lifestyle. Or else, as times moves by, you might not be moving at all.
