I hate when that happens.
I have found this helpful for me.
I print off both items in a large font in Word. When I stare at them side by side, the difference becomes clearer for me. Then I tend to confuse them less often.
I will also make up my own mnemonics.
For example, force and hot used to kill me. After I printed them off, I saw the difference. Now I never miss them because hot has flames under it making it hot.
