AS OF TODAY START TO BECOME THE PERSON YOU WANT TO BE.

Slowly start tweaking your habits. Become more self aware and mindful about what you do each day to achieve that.
Ask yourself - "Is it getting me closer to where I want to be, who I want to become?"
I got this great advice from a wonderful business coach yesterday, about journalling your intentions.
Apparently if you journal or write your intentions down on paper, and you look at them daily you have 80% more chance of achieving them.
You only have to put a few things down for that week, so its scalable. You don't want to overwhelm yourself
It could be that you're always late all the time and you've decided that this year you are going to make a concerted effort to be on time.
