Life is Like a Circle

Now i realize that life is like a spiral... It should be like that i think.
Before, i only know and believe that life is like a circle. Sometimes up - down and always round without any change...
I think it's totally wrong perseption, coz we can't expand and explore our ability if we agree that life is like circle.
So, i want my life is like a spiral... even every year we repeat same date, same month, same day but our life must be better than last year...
We have to grow up to reach next level and have bigger achievement than before.
Always think positif, forget all negatif things instead of being pessimistic, using our power mind in everything, then all d positif things will come and happen in our life...just believe it!
