Capital letters and full stops

I put a capital letter at the beginning of a sentence.  I put a capital letter after a full stop.  I also put a capital "I" when I am writing about myself.  It is tricky to remember to put capital letters and full stops.  I can proof-read and edit my work to help me remember to put capital letters and full stops.  Full stops go at the end of a sentence.  I am proud when I do really long story writing.
