This is my one word

My one word for me -I read this on Tara Sloan's and Pastor Deanna's blog- decided I was going to do it and choose my word- what is it you ask well if you think about it- you may guess before reading on.

This is the definition: to persist in anything undertaken; maintain a purpose in spite of difficulty, obstacles, or discouragement; continue steadfastly

Did you guess- here it is- cause I need to hang on to this word this year
