JUST DO IT
!
Mental fitness is very much like physical fitness. It takes a long time
and a lot of hard work to achieve it and maintain it. But it is worth
every bit of effort you put in. The payoff can be extraordinary!
When you begin the process of working on yourself, to create on
the
inside
a clear picture of what you want to enjoy on the 
outside
,
progress may be slow at first. But when you persist, when you keep
doing and saying the right things in the right way, you will before
too long get results out of all proportion to the efforts you put it.
There are no real limits to what you can be, do, and have, ex-
cept for the limits you place on yourself.You are a thoroughly good
and extremely talented person, and there is very little that you can-
not achieve if you want it intensely enough and work toward it long
enough and hard enough. The key is to begin today, and then 
never
give up!
