When I'm really struggling, I'll start my list with 2 items: 1) Write goal list, 2) Check off first item. Straight away I've done 2 things, and even though they're tiny, they give me a huge boost! So my best tip would be the following -

Write out your end goal
Write out the steps to obtain it
Break each step into 2 smaller steps so you cross them off faster

I keep mine on my smartphone, and set reminders for when each step should finish. It keeps me honest, for the most part
