As long as there's already the plan that you are visioning good result, then give it a try of following it. But if the second time and it doesn't make you productive.
Do the other thing that you think is better. In plans, you always have to make at least 2 or 3 so that you'll have contingency plans if the first one isn't good.
you're right. I always have plans a, b, and c. The dynamics in life are so variable that alternatives are really needed.
Having alternatives and options will make us prepared if something odd happens that didn't go along with the plan a that we've made.
Keep following those plans that you've made until you become efficient and effective with those.
