Time management is important in bitcoin if your really want to earn. In my case, everytime i have a spare time like break time or after work i spent it in bitcoin specifically in forum. I have no time browsing my fb acct. anymore, my focus is more on bitcoin.
That is one way to utilize every free moments. You have something already fixed for it and then you make sure you do everything as stipulated.
Someone like me with a lot of a busy schedule and so many things to do, I have always had a fixed to-do list with time fixed on each, which has really helped me to always achieve as much as possible in a single day and even look for some little free times I can still add some few things to make use of every available opportunity.
