Mindfulness so you can catch yourself procrastinating.

Educate yourself on emotional intelligence. Start asking yourself "how do I feel right now?". Usually there's a reason for you to delay tasks.

Write down your plan for the day. Write down your plan for the day. Write down your plan for the day. I can't stress this enough. It's stupid. It's simple. But for some reason it works.

Also, just do it.

Also, don't be afraid to take a bit of rest. Try to stick to a workable segment (example: I'll work for 30 minutes, rest, work for 30 minutes, rest), then increase the duration until you feel comfortable. Much easier to start with small chunks than big ones, it feels less daunting, thus making you less prone to procrastinate.
