Here is a list of very helpful things that I employ:
-- exercise everyday at least 45 minutes of cardio (even if it is just dancing around to music, it can lift the mood)
-- take 1-2 B-complex vitamins everyday (they help with my focus & motivation; huge help).
Take one in the morning & if my focus is slipping I take another around 2pm.
-- drink water all day, & limit my coffee to one cup in the morning & maybe one at lunch, but not everyday
-- eat a healthy diet with raw fruit, veggies, & whole grains
(caring enough about your body to take care of it can lower extra stress of preventable illness).
-- read anything 3 times
(a chapter, a whole book, an article, anything):
once to get familiar,
twice to take notes on the details & find important ideas,
and a third will imprint it on your mind and will actually let you connect this info to things you already know … this extra connection to established info that already has roots in your mind helps recall later.
-- when you start any task, dopamine will be released; this serves as a distraction to those of us with ptsd & related issues; it is very important to ride out this initial period of time at the beginning of tasks where you just want to find something else to do – timing is important for our focus to kick in.
It might take up to 45 minutes for real focus to happen, & when it does finally kick in, you might have to go back to the beginning of the task & start over (especially if it is reading). This was the reason I needed extra time on reading comprehension & essay-type exams. It is worth sticking out this initial lack of focus on the current task – ride it out & eventually your focus WILL kick in. It does take some time & practice.
-- memory: a few tricks to memory – I use colored pens, lists, charts, diagrams, & repetition
I write everything out that I need to remember using the above items … then write it again … then write it again until I can write it all out without needing to look at previous lists. It is work, but the results is worth the effort.
-- if you find yourself getting really really frustrated on one subject, it can be beneficial to work on easier subjects & go back to the harder ones. Try not to spend all your time stuck on one thing. Get the stuff you are able to get done first, then tackle the harder things.
-- if all else fails, ask for help.
