21 Day habit loop

I just need a one page about new habit reflection .. and the new habit is "going to the gym for exercising" 

The reflection page must address some of the following:

1-Do you consider your 21 Days a success or failure? Why?

2-Was your habit simple enough? Did your cue work?

3-Was yiur reward enough to motivate you? What performance barries did you encounter?

4- Would you use this process again to establish another new habit? Why or why not?

So Its all about writing a reflection of one page about a new habit
