What I find helps me the most is regimentation of my schedule. I've been most productive when I construct my day so that I always know what I'm supposed to be doing in order, if not a specific time.

For example, my daily schedule is:

• curating Steemit;
• reviewing my finances, paying bills, etc.;
• reviewing upcoming sports bets and record keeping;
• posting on Steemit;
• working out;

You get the idea...

When I have every day set up this way, I find the process to be the catalyst for concentration and execution. Its a groove or a rhythm, I guess...

I am far more productive this way, and I ensure that no one activity hijacks my day at the expense of other things I want, or need, to do...
