Once I was a laid back person too.
But I manage to break from this mould by setting
a goal just outside my reach. Not that high, just
enough so that I could step out a little bit out of
my comfort zone.
For example, being not a passionate reader, I found
it hard to concentrate.
So what I do is, I set a target to read like 5 pages
a day and followed by 15 minutes of taking action
from what I just learn by reading in the 5 pages.
And slowly now I increase it to two chapters per day.
Best Regards
Jenny
