Someone in another thread just posted this link and I think it might be one of the best things Ive found for myself to keep me focused on my goals and and whats in front of me in poker.

It has great things you can add to it that it will go over before you start each session like:

1) POker Goals- you can add long term, mid term, and short term goals that is reviews with you before you start your session.

2)Tech Leaks- Reminds you what to focus on during your session that you are struggling with

3)Mental leaks obviously

4)Possible distractions you need to remove before you start your session

5)Concentration-remind you of the things that helps you concentrate the best and focus at the best of your ability

6)Video- Review video before you start(your choice)

7)Article- Read over something you decide will get you focused on the task at hand before you start

8) Session timer(Awesome for taking that 10 minute break you said youd take 3 hours ago.  It says you need a 10 minute break every hour and a half min.

Brain Games to make sure your brain is sharp before you start(not part of warm up)

I would really suggest those who struggle at the beginning of their session to check this out bc I found that it really helped me today with my session.  I felt focused and reading hands well from the get go!!!
