We all make promises to ourselves that sometimes start with "Tomorrow I am going to... (insert goal/desire here)."
In my past I have stated the following:
Next week I am going to start running.
Tomorrow I am going to get back on track with weight watchers.
Next month I am going to start keeping my house clean.
Tonight I am going to wash my dishes.
Tonight, tomorrow, next week or next month comes and I have already forgotten my goal or I make an excuse as to why I can put it off another day. The only way I personally can ensure tonight comes without forgetting the stated goal is to begin now. I think the more reasonable our goals the easier it is to begin working toward those goals.
