reach the top

When you reach the top, thats when the climb begins.
                                                                                             Michael Caine

this means that when you reach the top is like when you you reach your goal and what you really want to do in life then when you reach that thats when your journey really begins.

How are you planning to reach your top?

live your best

you had better live your best and act your best and think your best today ; for today is the sure preparation for tomorrow and all other tomorrows that follow.     Hariet Martinea


i think this kinda means that the way you think, act, and live today might reflect your day tomorrow or the days after. like it could determine your moods and how you look at the day and how you carry yourself.

Do you think, act, and live good everyday?

younger today

You are younger today than you ever will be again. Make use of it for the sake of tomorrow.

This means that you are not going to stay young forever so you need to do things that young people do or that you need to not try to grow up so fast.

think wrongly

Think wrongly if you please, but in all cases think for yourself     author unknown


To me this means that you can think what you want or how you want  but do not let other people influence how you think.
